[LLVMdev] X86 -tailcallopt and C calling conversion
...imization when both caller
and callee have ccc,
even when it is optimized without an option -tailcallopt.
Is it intended or misoptimized?
In X86ISelLowering.cpp:X86TargetLowering::IsEligibleForTailCallOptimization():
if (GuaranteedTailCallOpt) {
if (IsTailCallConvention(CalleeCC) && CCMatch)
return true;
return false;
}
I know -tailcallopt changes calling conversion of fastcc to callee-pop.
ps. I am tweaking tailcallopt on Win64.

[klibc:master] dash: output: Fix clang warnings about GNU old-style field designator
...^~~~~~
.nextc =
...
-----------------------------------------------------------------------
Fix the issue bu using C99 initializers instead.
This should be safe and should not introduce any compatibility problems
as it is done already in other parts of the codebase, like
src/expand.c:ccmatch() and src/parser.c::readtoken1().

Fixed inverted char class matching
The return value of ccmatch was being treated as 0 or 1 but
it's actually zero or non-zero. This broke inverted character
class matching.

...de in X86TargetLowering::IsEligibleForTailCallOptimization() has this part:
// The callee has to preserve all registers the caller needs to preserve.
const X86RegisterInfo *TRI = Subtarget.getRegisterInfo();
const uint32_t *CallerPreserved = TRI->getCallPreservedMask(MF, CallerCC);
if (!CCMatch) {
const uint32_t *CalleePreserved = TRI->getCallPreservedMask(MF, CalleeCC);
if (!TRI->regmaskSubsetEqual(CallerPreserved, CalleePreserved))
return false;
}
which usually checks that this is fine. Maybe that code looks at the regmask of the calling convention rather than the...
