Reid Kleckner	e852ac7772	Revert "Don't count inreg params when mangling fastcall functions" ... This reverts commit r214981. I'm not sure what I was thinking when I wrote this. Testing with MSVC shows that this function is mangled to '@f@8': int __fastcall f(int a, int b); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220492 91177308-0d34-0410-b5e6-96231b3b80d8	2014-10-23 17:50:42 +00:00
Reid Kleckner	5d04e520c0	Don't count inreg params when mangling fastcall functions ... This is consistent with MSVC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214981 91177308-0d34-0410-b5e6-96231b3b80d8	2014-08-06 18:09:04 +00:00
Reid Kleckner	9902128e2a	Implement X86 code generation for musttail ... Currently, musttail codegen is relying on sibcall optimization, and reporting a fatal error if fails. Sibcall optimization fails when stack arguments need to be modified, which is insufficient for musttail. The logic for moving arguments in memory safely is already implemented for GuaranteedTailCallOpt. This change merely arranges for musttail calls to use it. No functional change for GuaranteedTailCallOpt.
