[gold][PATCH] Extend --compress-debug-sections in gold
H.J. Lu
hjl.tools@gmail.com
Wed Apr 15 12:06:00 GMT 2015
This patch extends --compress-debug-sections= with [zlib-gnu|zlib-gabi]
in gold. OK for master?
H.J.
* compressed_output.cc (zlib_compress): Add argument for
compression header size. Add compression header size to
header size.
(Output_compressed_section::set_final_data_size): Support
zlib-gnu and zlib-gabi compressions.
* options.h (compress_debug_sections): Add zlib-gnu and
zlib-gabi.
* output.h (Output_section::set_flags): New.
* testsuite/Makefile.am (check_PROGRAMS): Add
flagstest_compress_debug_sections_none,
flagstest_compress_debug_sections_gnu and
flagstest_compress_debug_sections_gabi.
(check_DATA): Add flagstest_compress_debug_sections_none.stdout.
flagstest_compress_debug_sections.stdout,
flagstest_compress_debug_sections.cmp,
flagstest_compress_debug_sections.check,
flagstest_compress_debug_sections_gnu.stdout,
flagstest_compress_debug_sections_gnu.cmp,
flagstest_compress_debug_sections_gnu.check,
flagstest_compress_debug_sections_gabi.stdout,
flagstest_compress_debug_sections_gabi.cmp and
flagstest_compress_debug_sections_gabi.check.
(flagstest_compress_debug_sections_none): New.
(flagstest_compress_debug_sections_none.stdout): Likewise.
(flagstest_compress_debug_sections.stdout): Likewise.
(flagstest_compress_debug_sections.check): Likewise.
(flagstest_compress_debug_sections.cmp): Likewise.
(flagstest_compress_debug_sections_gnu): Likewise.
(flagstest_compress_debug_sections_gnu.stdout): Likewise.
(flagstest_compress_debug_sections_gnu.check): Likewise.
(flagstest_compress_debug_sections_gnu.cmp): Likewise.
(flagstest_compress_debug_sections_gabi): Likewise.
(flagstest_compress_debug_sections_gabi.stdout): Likewise.
(flagstest_compress_debug_sections_gnu.check): Likewise.
(flagstest_compress_debug_sections_gnu.cmp): Likewise.
* testsuite/Makefile.in: Regenerated.
