2013-04-22Remove unused DwarfSectionOffsetDirective stringMatt Arsenault
The value isn't actually used, and setting it emits a COFF specific directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180064 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-07Fix alignment of .comm and .lcomm on mingw32.Benjamin Kramer
For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't use the same setting for both. Fix this by reintroducing the LCOMM enum. I verified this against mingw's gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163420 91177308-0d34-0410-b5e6-96231b3b80d8

bytes, not power of 2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163405 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-07MC: Overhaul handling of .lcommBenjamin Kramer
- Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163395 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-18Refactor data-in-code annotations.Jim Grosbach
Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-29MC/X86/COFF: Allow quotes in names when targeting MS/Windows,Michael J. Spencer
as MC is the only assembler we support. This splits MS/Windows and GNU/Windows ASM infos into two seperate classes. While there is currently only one difference, full MS C++ ABI support will require many more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145409 91177308-0d34-0410-b5e6-96231b3b80d8

modes. These are used by disassemblers to provide better disassembly, particularly on targets like ARM Thumb that like to intermingle data in the TEXT segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141135 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-01Don't drop alignment info on local common symbols.Benjamin Kramer
- On COFF the .lcomm directive has an alignment argument. - On ELF we fall back to .local + .comm Based on a patch by NAKAMURA Takumi. Fixes PR9337, PR9483 and PR10128. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138976 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-04eliminate the magic AbsoluteDebugSectionOffsets MAI hook,Chris Lattner
which is really a property of the section being referenced. Add a predicate to MCSection to replace it. Yay for reduction in magic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100367 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26use EmitLinkage for functions as well as globals. One outputChris Lattner
change is that we now use ".linkonce discard" for global variables instead of ".linkonce samesize". These should be the same, just less strict. If anyone is interested in mcizing MCSection for COFF targets, this should be easy to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94623 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Eliminate SetDirective, and replace it with HasSetDirective.Chris Lattner
Default HasSetDirective to true, since most targets have it. The targets that claim to not have it probably do, or it is spelled differently. These include Blackfin, Mips, Alpha, and PIC16. All of these except pic16 are normal ELF targets, so they almost certainly have it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19give MCAsmInfo a 'has little endian' bit. This is unfortunate, butChris Lattner
I really want clients of the streamer to be able to say "emit this 64-bit integer" and have it get broken down right by the streamer. I may change this in the future, we'll see how it works out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93934 91177308-0d34-0410-b5e6-96231b3b80d8
