X-Git-Tag: binutils-2_29~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=991a4012c56f09d9ea7f0b44e47231693a774e94;p=thirdparty%2Fbinutils-gdb.git

PR ld/21529: Use a linker script to limit output with the test case

Complement commit d9409498813c ("Add a testcase for PR ld/21529") and
use a linker script to prevent an inter-segment gap arranged by the
default linker script associated with some targets such as `rx-elf':

$ ld -e main -o tmpdir/dump-elf tmpdir/pr21529.o
$ readelf -l tmpdir/dump-elf
Elf file type is EXEC (Executable file)
Entry point 0x10000004
There are 2 program headers, starting at offset 52

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x001000 0x10000000 0x10000000 0x00008 0x00008 R E 0x1000
  LOAD           0x001ffc 0xbffffffc 0xbffffffc 0x00004 0x00004 RW  0x1000

 Section to Segment mapping:
  Segment Sections...
   00     .text
   01     .stack
$

and converted to padding with the use of the binary BFD for output from
producing unreasonably large files.
