+@item -flto
+@opindex flto
+This option runs the standard link-time optimizer. When invoked
+with source code, it generates GIMPLE (one of GCC's internal
+representations) and writes it to special ELF sections in the object
+file. When the object files are linked together, all the function
+bodies are read from these ELF sections and instantiated as if they
+had been part of the same translation unit.
+
+To use the link-timer optimizer, @option{-flto} needs to be specified at
+compile time and during the final link. For example,
+
+@smallexample
+gcc -c -O2 -flto foo.c
+gcc -c -O2 -flto bar.c
+gcc -o myprog -flto -O2 foo.o bar.o
+@end smallexample
+
+The first two invocations to GCC will save a bytecode representation
+of GIMPLE into special ELF sections inside @file{foo.o} and
+@file{bar.o}. The final invocation will read the GIMPLE bytecode from
+@file{foo.o} and @file{bar.o}, merge the two files into a single
+internal image, and compile the result as usual. Since both
+@file{foo.o} and @file{bar.o} are merged into a single image, this
+causes all the inter-procedural analyses and optimizations in GCC to
+work across the two files as if they were a single one. This means,
+for example, that the inliner will be able to inline functions in
+@file{bar.o} into functions in @file{foo.o} and vice-versa.
+
+Another (simpler) way to enable link-time optimization is,
+
+@smallexample
+gcc -o myprog -flto -O2 foo.c bar.c
+@end smallexample
+
+The above will generate bytecode for @file{foo.c} and @file{bar.c},
+merge them together into a single GIMPLE representation and optimize
+them as usual to produce @file{myprog}.
+
+The only important thing to keep in mind is that to enable link-time
+optimizations the @option{-flto} flag needs to be passed to both the
+compile and the link commands.
+
+Note that when a file is compiled with @option{-flto}, the generated
+object file will be larger than a regular object file because it will
+contain GIMPLE bytecodes and the usual final code. This means that
+object files with LTO information can be linked as a normal object
+file. So, in the previous example, if the final link is done with
+
+@smallexample
+gcc -o myprog foo.o bar.o
+@end smallexample
+
+The only difference will be that no inter-procedural optimizations
+will be applied to produce @file{myprog}. The two object files
+@file{foo.o} and @file{bar.o} will be simply sent to the regular
+linker.
+
+Additionally, the optimization flags used to compile individual files
+are not necessarily related to those used at link-time. For instance,
+
+@smallexample
+gcc -c -O0 -flto foo.c
+gcc -c -O0 -flto bar.c
+gcc -o myprog -flto -O3 foo.o bar.o
+@end smallexample
+
+This will produce individual object files with unoptimized assembler
+code, but the resulting binary @file{myprog} will be optimized at
+@option{-O3}. Now, if the final binary is generated without
+@option{-flto}, then @file{myprog} will not be optimized.
+
+When producing the final binary with @option{-flto}, GCC will only
+apply link-time optimizations to those files that contain bytecode.
+Therefore, you can mix and match object files and libraries with
+GIMPLE bytecodes and final object code. GCC will automatically select
+which files to optimize in LTO mode and which files to link without
+further processing.
+
+There are some code generation flags that GCC will preserve when
+generating bytecodes, as they need to be used during the final link
+stage. Currently, the following options are saved into the GIMPLE
+bytecode files: @option{-fPIC}, @option{-fcommon} and all the
+@option{-m} target flags.
+
+At link time, these options are read-in and reapplied. Note that the
+current implementation makes no attempt at recognizing conflicting
+values for these options. If two or more files have a conflicting
+value (e.g., one file is compiled with @option{-fPIC} and another
+isn't), the compiler will simply use the last value read from the
+bytecode files. It is recommended, then, that all the files
+participating in the same link be compiled with the same options.
+
+Another feature of LTO is that it is possible to apply interprocedural
+optimizations on files written in different languages. This requires
+some support in the language front end. Currently, the C, C++ and
+Fortran front ends are capable of emitting GIMPLE bytecodes, so
+something like this should work
+
+@smallexample
+gcc -c -flto foo.c
+g++ -c -flto bar.cc
+gfortran -c -flto baz.f90
+g++ -o myprog -flto -O3 foo.o bar.o baz.o -lgfortran
+@end smallexample
+
+Notice that the final link is done with @command{g++} to get the C++
+runtime libraries and @option{-lgfortran} is added to get the Fortran
+runtime libraries. In general, when mixing languages in LTO mode, you
+should use the same link command used when mixing languages in a
+regular (non-LTO) compilation. This means that if your build process
+was mixing languages before, all you need to add is @option{-flto} to
+all the compile and link commands.
+
+If object files containing GIMPLE bytecode are stored in a library
+archive, say @file{libfoo.a}, it is possible to extract and use them
+in an LTO link if you are using @command{gold} as the linker (which,
+in turn requires GCC to be configured with @option{--enable-gold}).
+To enable this feature, use the flag @option{-use-linker-plugin} at
+link-time:
+
+@smallexample
+gcc -o myprog -O2 -flto -use-linker-plugin a.o b.o -lfoo
+@end smallexample
+
+With the linker plugin enabled, @command{gold} will extract the needed
+GIMPLE files from @file{libfoo.a} and pass them on to the running GCC
+to make them part of the aggregated GIMPLE image to be optimized.
+
+If you are not using @command{gold} and/or do not specify
+@option{-use-linker-plugin} then the objects inside @file{libfoo.a}
+will be extracted and linked as usual, but they will not participate
+in the LTO optimization process.
+
+Regarding portability: the current implementation of LTO makes no
+attempt at generating bytecode that can be ported between different
+types of hosts. The bytecode files are versioned and there is a
+strict version check, so bytecode files generated in one version of
+GCC will not work with an older/newer version of GCC.
+
+This option is disabled by default.
+
+@item -fwhopr
+@opindex fwhopr
+This option is identical in functionality to @option{-flto} but it
+differs in how the final link stage is executed. Instead of loading
+all the function bodies in memory, the callgraph is analyzed and
+optimization decisions are made (whole program analysis or WPA). Once
+optimization decisions are made, the callgraph is partitioned and the
+different sections are compiled separately (local transformations or
+LTRANS)@. This process allows optimizations on very large programs
+that otherwise would not fit in memory. This option enables
+@option{-fwpa} and @option{-fltrans} automatically.
+
+Disabled by default.
+
+@item -fwpa
+@opindex fwpa
+This is an internal option used by GCC when compiling with
+@option{-fwhopr}. You should never need to use it.
+
+This option runs the link-time optimizer in the whole-program-analysis
+(WPA) mode, which reads in summary information from all inputs and
+performs a whole-program analysis based on summary information only.
+It generates object files for subsequent runs of the link-time
+optimizer where individual object files are optimized using both
+summary information from the WPA mode and the actual function bodies.
+It then drives the LTRANS phase.
+
+Disabled by default.
+
+@item -fltrans
+@opindex fltrans
+This is an internal option used by GCC when compiling with
+@option{-fwhopr}. You should never need to use it.
+
+This option runs the link-time optimizer in the local-transformation (LTRANS)
+mode, which reads in output from a previous run of the LTO in WPA mode.
+In the LTRANS mode, LTO optimizes an object and produces the final assembly.
+
+Disabled by default.
+
+@item -fltrans-output-list=@var{file}
+@opindex fltrans-output-list
+This is an internal option used by GCC when compiling with
+@option{-fwhopr}. You should never need to use it.
+
+This option specifies a file to which the names of LTRANS output files are
+written. This option is only meaningful in conjunction with @option{-fwpa}.
+
+Disabled by default.
+
+@item -flto-compression-level=@var{n}
+This option specifies the level of compression used for intermediate
+language written to LTO object files, and is only meaningful in
+conjunction with LTO mode (@option{-fwhopr}, @option{-flto}). Valid
+values are 0 (no compression) to 9 (maximum compression). Values
+outside this range are clamped to either 0 or 9. If the option is not
+given, a default balanced compression setting is used.
+
+@item -flto-report
+Prints a report with internal details on the workings of the link-time
+optimizer. The contents of this report vary from version to version,
+it is meant to be useful to GCC developers when processing object
+files in LTO mode (via @option{-fwhopr} or @option{-flto}).
+
+Disabled by default.
+
+@item -use-linker-plugin
+Enables the extraction of objects with GIMPLE bytecode information
+from library archives. This option relies on features available only
+in @command{gold}, so to use this you must configure GCC with
+@option{--enable-gold}. See @option{-flto} for a description on the
+effect of this flag and how to use it.

+@subsection Support for testing link-time optimizations
+
+Tests for link-time optimizations usually require multiple source files
+that are compiled separately, perhaps with different sets of options.
+There are several special-purpose test directives used for these tests.
+
+@table @code
+@item @{ dg-lto-do @var{do-what-keyword} @}
+@var{do-what-keyword} specifies how the test is compiled and whether
+it is executed. It is one of:
+
+@table @code
+@item assemble
+Compile with @option{-c} to produce a relocatable object file.
+@item link
+Compile, assemble, and link to produce an executable file.
+@item run
+Produce and run an executable file, which is expected to return
+an exit code of 0.
+@end table
+
+The default is @code{assemble}. That can be overridden for a set of
+tests by redefining @code{dg-do-what-default} within the @code{.exp}
+file for those tests.
+

+
+ 1) The header.
+ 2) FIELD_DECLS.
+ 3) FUNCTION_DECLS.
+ 4) global VAR_DECLS.
+ 5) type_decls
+ 6) types.
+ 7) Names for the labels that have names
+ 8) The SSA names.
+ 9) The control flow graph.
+ 10-11)Gimple for local decls.
+ 12) Gimple for the function.
+ 13) Strings.
+
+ 1) THE HEADER.
+ 2-6) THE GLOBAL DECLS AND TYPES.
+
+ The global decls and types are encoded in the same way. For each
+ entry, there is word with the offset within the section to the
+ entry.
+
+ 7) THE LABEL NAMES.
+
+ Since most labels do not have names, this section my be of zero
+ length. It consists of an array of string table references, one
+ per label. In the lto code, the labels are given either
+ positive or negative indexes. the positive ones have names and
+ the negative ones do not. The positive index can be used to
+ find the name in this array.
+
+ 9) THE CFG.
+
+ 10) Index into the local decls. Since local decls can have local
+ decls inside them, they must be read in randomly in order to
+ properly restore them.
+
+ 11-12) GIMPLE FOR THE LOCAL DECLS AND THE FUNCTION BODY.
+
+ The gimple consists of a set of records.
+
+ THE FUNCTION
+
+ At the top level of (8) is the function. It consists of five
+ pieces:
+
+ LTO_function - The tag.
+ eh tree - This is all of the exception handling regions
+ put out in a post order traversial of the
+ tree. Siblings are output as lists terminated
+ by a 0. The set of fields matches the fields
+ defined in except.c.
+
+ last_basic_block - in uleb128 form.
+
+ basic blocks - This is the set of basic blocks.
+
+ zero - The termination of the basic blocks.
+
+ BASIC BLOCKS
+
+ There are two forms of basic blocks depending on if they are
+ empty or not.
+
+ The basic block consists of:
+
+ LTO_bb1 or LTO_bb0 - The tag.
+
+ bb->index - the index in uleb128 form.
+
+ #succs - The number of successors un uleb128 form.
+
+ the successors - For each edge, a pair. The first of the
+ pair is the index of the successor in
+ uleb128 form and the second are the flags in
+ uleb128 form.
+
+ the statements - A gimple tree, as described above.
+ These are only present for LTO_BB1.
+ Following each statement is an optional
+ exception handling record LTO_eh_region
+ which contains the region number (for
+ regions >= 0).
+
+ zero - This is only present for LTO_BB1 and is used
+ to terminate the statements and exception
+ regions within this block.
+
+ 12) STRINGS
+
+ String are represented in the table as pairs, a length in ULEB128
+ form followed by the data for the string. */

+This directory contains tests for link-time optimization (LTO).
+Tests in this directory may span multiple files, so the naming of
+the files is significant.
+
+The name of every file must end with '_N' where N is an integer.
+All the files with the same name base and different _N suffixes
+will be compiled separately and linked together to form the final
+executable.
+
+By default, each set of files will be compiled with list of
+options listed in LTO_OPTIONS (../../lib/lto.exp), which can be
+overwritten in the shell environment or using the 'dg-lto-options'
+command in the main file of the set (i.e., the file with _0
+suffix).

+For example, given the files a_0.C a_1.C a_2.C, they will be
+compiled as:
+
+$ g++ -c <flags> a_0.C
+$ g++ -c <flags> a_1.C
+$ g++ -c <flags> a_2.C
+$ g++ -o <executable> a_0.o a_1.o a_2.o
+
+Tests that do not need more than one file are a special case
+where there is a single file named 'foo_0.C'.
+
+The only supported dg-lto-do option are 'compile', 'run' and 'link'.
+Additionally, these can only be used in the main file. If
+'compile' is used, only the individual object files are
+generated. If 'link' is used, the final executable is generated
+but not executed (in this case, function main() needs to exist
+but it does not need to do anything). If 'run' is used, the
+final executable is generated and the resulting binary executed.
+
+The default value for dg-lto-do is 'run'.

+This directory contains tests for link-time optimization (LTO).
+Tests in this directory may span multiple files, so the naming of
+the files is significant.
+
+The name of every file must end with '_N' where N is an integer.
+All the files with the same name base and different _N suffixes
+will be compiled separately and linked together to form the final
+executable.
+
+By default, each set of files will be compiled with list of
+options listed in LTO_OPTIONS (../../lib/lto.exp), which can be
+overwritten in the shell environment or using the 'dg-lto-options'
+command in the main file of the set (i.e., the file with _0
+suffix).
+
+For example, given the files a_0.C a_1.C a_2.C, they will be
+compiled as:
+
+$ g++ -c <flags> a_0.C
+$ g++ -c <flags> a_1.C
+$ g++ -c <flags> a_2.C
+$ g++ -o <executable> a_0.o a_1.o a_2.o
+
+Tests that do not need more than one file are a special case
+where there is a single file named 'foo_0.C'.
+
+The only supported dg-lto-do option are 'assemble', 'run' and 'link'.
+Additionally, these can only be used in the main file. If
+'assemble' is used, only the individual object files are
+generated. If 'link' is used, the final executable is generated
+but not executed (in this case, function main() needs to exist
+but it does not need to do anything). If 'run' is used, the
+final executable is generated and the resulting binary executed.
+
+The default value for dg-lto-do is 'run'.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+\`configure' configures LTO plugin for ld 0.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ LIBELFLIBS How to link libelf
+ LIBELFINC How to find libelf include files
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
