* x86_64 ABI: "is passed in regs" computation for va_arg was broken forDaniel Dunbar2009-02-181-1/+1
| | | | | | | | things passed in mixed registers. This knocks out 8 x86_64 failures. llvm-svn: 64958
* x86_64 ABI: Two bug fixes.Daniel Dunbar2009-02-181-4/+36
| | | | | | | | | | | | | | | | | | 1. Return of _Complex long double used wrong type. 2. va_arg of types passed in two SSE registers didn't account for extra space in register save area. Down to 18 failures on gcc/compat/x86_64. Combined 32/64 results are: -- === gcc Summary === # of expected passes 1292 # of unexpected failures 34 # of unsupported tests 2 -- llvm-svn: 64880

* x86_64 ABI: Pass simple types directly when possible. This isDaniel Dunbar2009-02-141-2/+32
| | | | | | | important for both keeping the generated LLVM simple and for ensuring that integer types are passed/promoted correctly. llvm-svn: 64529
* x86_64 ABI: Support va_arg passed in mixed registers.Daniel Dunbar2009-02-131-1/+22
| | | | | | - Now at 1274 passes on gcc compat suite vs 1262. llvm-svn: 64469
* x86_64: Initial varargs support.Daniel Dunbar2009-02-121-1/+153
| | | | | | | | | | | | | | | | | | | | | | | | | - Doesn't yet handle case where values are passed in mixed (general purpose & floating point) registers; otherwise largely functional. Code still needs some cleaning.

* ABI: Correctly handle load/store of values which have a different LLVMDaniel Dunbar2009-02-101-21/+22
| | | | | | | | | memory representation (e.g., bool). - This upgrades (downgrades) MultiSource/Applications/ClamAV/clamscan to a miscompile and fixes SingleSource/UnitTests/2003-05-31-CastToBool. llvm-svn: 64194
* Make sure to initialize local variables, even if they were ignored byDaniel Dunbar2009-02-101-0/+7
| | | | | | ABI. llvm-svn: 64187
* Set load/store alignment when doing ABI coercions.Daniel Dunbar2009-02-071-4/+14
| | | | | | | | | | | | - Currently, this is producing poor code, but we prefer correctness to performance for now. Eventually we should be able to generally avoid having to set the alignment when we control the alignment of the alloca. - This knocks out 33/1000 failures on my single argument ABI tests, down to 22/1000 and 18 of these appear to be gcc bugs. Woot. llvm-svn: 64001
* Implement Direct ABIInfo semantics.Daniel Dunbar2009-02-051-17/+29
| | | | | | | | - No intended functionality change, this is essentially enabling direct passing of complex and aggregate values, which no ABI is using. llvm-svn: 63863
* Simplify test for whether we need an alloca to hold an indirect returnDaniel Dunbar2009-02-051-11/+1
| | | | | | | value. - No functionality change. llvm-svn: 63859
* Implement ABI Indirect sematics for arguments.Daniel Dunbar2009-02-051-6/+32
| | | | | | | | - No intended functionality change, all current ABI implementations were only using indirect for complex/aggregate types, which were being passed indirectly with the Direct ABIInfo kind. llvm-svn: 63858
* Merge ABIInfo StructRet/ByVal into Indirect. Daniel Dunbar2009-02-051-46/+30
| | | | | | - No (intended) functionality change, the semantic changes are to come. llvm-svn: 63850

* Temporarily disable caching of ABI results; this is going horriblyDaniel Dunbar2009-02-041-1/+3

* Add asserts that the function signature matches the other arguments provideDaniel Dunbar2009-02-041-0/+4

* x86_64 ABI: Initial implementation of ABI compliant parameter passing.Daniel Dunbar2009-02-031-18/+119
| | | | | | | | | | | - Now only 27/500 failures on ABITest single argument tests; from 350/500. :) - As with return types, a large percentage of these are likely to be gcc bugs, not yet reviewed. Also, fix bug in handling of Ignore ABI type in argument lists. llvm-svn: 63654
* ABI handling: Implement coercion for argument types (in addition toDaniel Dunbar2009-02-031-4/+39
| | | | | | return types). llvm-svn: 63645
* Change ABIInfo to compute information for a full signature at a timeDaniel Dunbar2009-02-031-41/+38
| | | | | | (the main point of this restructing). llvm-svn: 63619
* Remove ABIArgInfo::Default kind, ABI is now responsible for specifyingDaniel Dunbar2009-02-031-33/+28
| | | | | | acceptable kind with more precise semantics. llvm-svn: 63617
* Add ABIArgInfo::Direct kind, which passes arguments using whatever theDaniel Dunbar2009-02-031-1/+18
| | | | | | | native IRgen type is. This is like Default, but without any extra semantics (like automatic tweaking of structures or void). llvm-svn: 63615

| | | | llvm-svn: 63612
* Move ABIArgInfo into CGFunctionInfo, computed on creation.Daniel Dunbar2009-02-031-25/+31

| | | | llvm-svn: 63571
* Thread CGFunctionInfo construction through CodeGenTypes.Daniel Dunbar2009-02-021-26/+46

* More ABI API cleanup.Daniel Dunbar2009-02-021-13/+12
| | | | | | | - Lift CGFunctionInfo creation above ReturnTypeUsesSret and EmitFunction{Epi,Pro}log. llvm-svn: 63553
* ABI handling API changes.Daniel Dunbar2009-02-021-29/+22
| | | | | | | | | | | - Lift CGFunctionInfo creation up to callers of EmitCall. - Move isVariadic bit out of CGFunctionInfo, take as argument to GetFunctionType instead. No functionality change. llvm-svn: 63550
