COFF: Emit a symbol table if /debug is specified Providing a symbol table in the executable is quite useful when debugging a fully-linked executable without having to reconstruct one from DWARF. Differential Revision: http://reviews.llvm.org/D11023 llvm-svn: 241689

# RUN: llvm-readobj -symbols %t.exe | FileCheck %s
COFF: Fix bug that not all symbols were written to symtab if /opt:noref. Only live symbols are written to the symbol table. Because isLive() returned false if dead-stripping was disabled entirely, only non-COMDAT sections were written to the symbol table. This patch fixes the issue. llvm-svn: 247856

2015-07-09 00:37:50 +08:00
COFF: Add /nosymtab command line option. This is an LLD extension to MSVC link.exe command line. MSVC linker does not write symbol tables for executables. We do unless no /debug option is given. There's a situation that we want to enable debug info but don't want to emit the symbol table. One example is when we are comparing output file size. With this patch, you can tell the linker to not create a symbol table by just specifying /nosymtab. llvm-svn: 248225
