Summary: When generating MIPS assembly, LLVM always overrides the default assembler options by emitting the '.set noreorder', '.set nomacro' and '.set noat' directives, while GCC uses the default options if an assembly-level function contains inline assembly code. This becomes a problem when the code generated by LLVM is interleaved with inline assembly which assumes GCC-like assembler options (from Linux, for example). This patch fixes these conflicts by setting the appropriate assembler options at the beginning of an inline asm block and popping them at the end.

Summary: -mno-odd-spreg prohibits the use of odd-numbered single-precision floating point registers. However, vector insert/extract was still using them when manipulating the subregisters of an MSA register. Fixed this by ensuring that insertion/extraction is only performed on even-numbered vector registers when -mno-odd-spreg is given.

Summary: This patch enables code generation for the MIPS II target. Pre-Mips32 targets don't have the MUL instruction, so we add the correspondent pattern that uses the MULT/MFLO combination in order to retrieve the product. This is WIP as we don't support code generation for select nodes due to the lack of conditional-move instructions.

Summary: Mips Linux uses $gp to hold a pointer to thread info structure and accesses it with a named register. This makes this work for LLVM. The N32 ABI doesn't quite work yet since the frontend generates incorrect IR for this case. It neglects to truncate the 64-bit GPR to a 32-bit value before converting to a pointer. Given correct IR (as in the testcase in this patch), it works correctly.

2014-12-31irgen: modify the ABI to use init guards instead of priorityPeter Collingbourne4-11/+92
The new ABI is simpler for use cases such as dynamically loaded packages. The calling convention for import functions is similar to what go/ssa would produce if BareInits were cleared. However, simply clearing this flag causes two additional issues: 1) We would need to special case the 'init$guard' variable (see discussion in https://codereview.appspot.com/78780043/). 2) The call to __go_register_gc_roots needs to appear in the right place, i.e. after the guard check. Making this check appear in the right place with non-bare inits seems unreliable at best. So we keep BareInits set and generate the necessary code manually. It is still possible to get the old ABI by specifying a path to a gccgo installation. Differential Revision: http://reviews.llvm.org/D6804 llvm-svn: 225030

2014-12-30DebugInfo: Omit is_stmt from line table entries on the same line.David Blaikie4-4/+87
GCC does this for non-zero discriminators and since GCC doesn't produce column info, that was the only place it comes up there. For LLVM, since we can emit discriminators and/or column info, it makes more sense to invert the condition and just test for changes in line number. This should resolve at least some of the GDB 7.5 test suite failures created by recent Clang changes that increase the location fidelity (which, since Clang defaults to including column info on Linux by default created a bunch of cases that confused GDB). In theory we could do this better/differently by grouping actual source statements together in a similar manner to the way lexical scopes are handled but given that GDB isn't really in a position to consume that (& users are probably somewhat used to different lines being different 'statements') this seems the safest and cheapest change. (I'm concerned that doing this 'right' would bloat the debugloc data even further - something Duncan's working hard to address) llvm-svn: 225011
