COFF: Remove redundant options from tests. llvm-svn: 238670
2015-05-31 12:21:30 +08:00
# RUN: yaml2obj < %s > %t.obj
COFF: Stop emitting a non-standard COFF symbol table into PEs. Now that our support for PDB emission is reasonably good, there is no longer a need to emit a COFF symbol table. Also fix a bug where we would fail to emit a string table for long section names if /debug was not specified. Differential Revision: https://reviews.llvm.org/D40189 llvm-svn: 318548
2017-11-18 03:51:20 +08:00
# RUN: lld-link /out:%t.exe /entry:main %t.obj
[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651

COFF: Support long section name. Section names were truncated to 8 bytes because the section table's name field is 8 byte long. This patch creates the string table to store long names. llvm-svn: 238661
2015-05-31 03:09:50 +08:00
[COFF] Don't write long section names for sections that will be mapped at runtime Sections that will be mapped at runtime will only have the short section name available, since the string table it points into isn't mapped. Therefore prefer truncating those names over writing a long name that is unavailable at runtime. This allows libunwind to find the .eh_frame section at runtime even if the module was built with debug info enabled. Differential Revision: https://reviews.llvm.org/D40025 llvm-svn: 318391

COFF: Fix logic to find default entry name or subsystem. The previous logic to find default entry name or subsystem does not seem correct (i.e. was not compatible with MSVC linker). Previously, default entry name was inferred from CRT functions and user-defined entry functions. Subsystem was inferred from CRT functions. Default entry name and subsystem are now inferred based on the following table. Note that we no longer use CRT functions to infer them. Entry name Subsystem main mainCRTStartup console wmain wmainCRTStartup console WinMain WinMainCRTStartup windows wWinMain wWinMainCRTStartup windows llvm-svn: 240922

[yaml2obj] Updating LLD tests to account for LLVM r273915 This removed the -format flag from yaml2obj in favor of YAML tags. llvm-svn: 273920
