To clear the instruction cache when a trampoline is initialized, define

-
-@table @code
-@findex INSN_CACHE_SIZE
-@item INSN_CACHE_SIZE
-The total size in bytes of the cache.
-
-@findex INSN_CACHE_LINE_WIDTH
-@item INSN_CACHE_LINE_WIDTH
-The length in bytes of each cache line. The cache is divided into cache
-lines which are disjoint slots, each holding a contiguous chunk of data
-fetched from memory. Each time data is brought into the cache, an
-entire line is read at once. The data loaded into a cache line is
-always aligned on a boundary equal to the line size.
-
-@findex INSN_CACHE_DEPTH
-@item INSN_CACHE_DEPTH
-The number of alternative cache lines that can hold any particular memory
-location.
-@end table

-Alternatively, if the machine has system calls or instructions to clear
-the instruction cache directly, you can define the following macro.
+the following macro.
@table @code
@findex CLEAR_INSN_CACHE
@item CLEAR_INSN_CACHE (@var{beg}, @var{end})
If defined, expands to a C expression clearing the @emph{instruction
-cache} in the specified interval. If it is not defined, and the macro
-@code{INSN_CACHE_SIZE} is defined, some generic code is generated to clear the
-cache. The definition of this macro would typically be a series of

To use a standard subroutine, define the following macro. In addition,
in DBX format, the debugging information entirely follows the assembler
code.
-@findex DBX_LBRAC_FIRST
-@item DBX_LBRAC_FIRST
-Define this macro if the @code{N_LBRAC} symbol for a block should
-precede the debugging information for variables and functions defined in
-that block. Normally, in DBX format, the @code{N_LBRAC} symbol comes
-first.
-
@findex DBX_BLOCKS_FUNCTION_RELATIVE
@item DBX_BLOCKS_FUNCTION_RELATIVE
Define this macro if the value of a symbol describing the scope of a
Define this macro if the target machine requires special handling to
output an @code{N_FUN} entry for the function @var{decl}.
-@findex DBX_OUTPUT_ENUM
-@item DBX_OUTPUT_ENUM (@var{stream}, @var{type})
-Define this macro if the target machine requires special handling to
-output an enumeration type. The definition should be a C statement
-(sans semicolon) to output the appropriate information to @var{stream}
-for the type @var{type}.
-
@findex DBX_OUTPUT_FUNCTION_END
@item DBX_OUTPUT_FUNCTION_END (@var{stream}, @var{function})
Define this macro if the target machine requires special output at the
This describes file names in DBX format.
@table @code
-@findex DBX_WORKING_DIRECTORY
-@item DBX_WORKING_DIRECTORY
-Define this if DBX wants to have the current directory recorded in each
-object file.
-
-Note that the working directory is always recorded if GDB extensions are
-enabled.
-
@findex DBX_OUTPUT_MAIN_SOURCE_FILENAME
@item DBX_OUTPUT_MAIN_SOURCE_FILENAME (@var{stream}, @var{name})
A C statement to output DBX debugging information to the stdio stream
If you don't define this macro, nothing special is output at the end
of compilation, which is correct for most machines.
-
-@findex DBX_OUTPUT_SOURCE_FILENAME
-@item DBX_OUTPUT_SOURCE_FILENAME (@var{stream}, @var{name})
-A C statement to output DBX debugging information to the stdio stream
-@var{stream} which indicates that file @var{name} is the current source
-file. This output is generated each time input shifts to a different
-source file as a result of @samp{#include}, the end of an included file,
-or a @samp{#line} command.
-
-This macro need not be defined if the standard form of output
-for DBX debugging information is appropriate.
