This is the first step to fix pr17918. It extends the .section directive a bit, inspired by what the ELF one looks like. The problem with using linkonce is that given .section foo .linkonce.... .section foo .linkonce we would already have switched sections when getting to .linkonce. The cleanest solution seems to be to add the comdat information in the .section itself. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195822 91177308-0d34-0410-b5e6-96231b3b80d8

* MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asmHans Wennborg2013-10-181-0/+38
| | | | | | | | | | | | | | | | | | | | This is another (final?) stab at making us able to parse our own asm output on Windows. Symbols on Windows often contain @'s and ?'s in their names. Our asm parser didn't like this. ?'s were not allowed, and @'s were intepreted as trying to reference PLT/GOT/etc. We can't just add quotes around the bad names, since e.g. for MinGW, we use gas to assemble, and it doesn't like quotes in some places (notably in .def directives). This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS assembly.

* Re-commit r192758 - MC: quote tricky symbol names in asm outputHans Wennborg2013-10-171-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | The reason this got reverted was that the @feat.00 symbol which was emitted for every TU became quoted, and on cygwin/mingw we use the gas assembler which couldn't handle the quotes. This commit fixes the problem by only emitting @feat.00 for win32, where we use clang -cc1as to assemble. gas would just drop this symbol anyway, so there is no loss there. With @feat.00 gone, there shouldn't be quoted symbols showing up on cygwin since it uses the Itanium ABI, which doesn't put these funny characters in symbols. > Because of win32 mangling, we produce symbol and section names with > funny characters in them, most notably @ characters. > > MC would choke on trying to parse its own assembly output.

* MC: Better handling of tricky symbol and section namesHans Wennborg2013-10-161-0/+20
| | | | | | | | | | | | | | | | | Because of win32 mangling, we produce symbol and section names with funny characters in them, most notably @ characters. MC would choke on trying to parse its own assembly output. This patch addresses that by: - Making @ trigger quoting of symbol names - Also quote section names in the same way - Just parse section names like other identifiers (to allow for quotes) - Don't assume @ signifies a symbol variant if it is in a string.

* COFF: Ensure that objects produced by LLVM link with /safesehReid Kleckner2013-09-171-0/+13
| | | | | | | | | | | | | | | | | | | | Summary: We indicate that the object files are safe by emitting a @feat.00 absolute address symbol. The address is presumably interpreted as a bitfield of features that the compiler would like to enable. Bit 0 is documented in the PE COFF spec to opt in to "registered SEH", which is what /safeseh enables. LLVM's object files are safe by default because LLVM doesn't know how to produce SEH handlers.

| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8
