2008-03-11If there are multiple register classes that a register belongs to, return ↵Evan Cheng
the super-class (e.g. on x86, returns GR32, not GR32_). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48220 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48219 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-11When the register allocator runs out of registers, spill a physical register ↵Evan Cheng
around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48218 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-11Change the model for FP Stack return to use fp operands on the Chris Lattner
RET instruction instead of using FpSET_ST0_32. This also generalizes the code to handling returning of multiple FP results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48209 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-11Generalize ExpandIntToFP to handle the case where the operand is legalDan Gohman
and it's the result that requires expansion. This code is a little confusing because the TargetLoweringInfo tables for [US]INT_TO_FP use the operand type (the integer type) rather than the result type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48206 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-10Disable prolog code that aligns the stack when aDale Johannesen
local object of >16 byte alignment exists. It does not work and getting it to work is not trivial, as explained in the comment. This fixes all the remaining ppc32 failures in the struct-layout-1 part of the gcc testsuite. (gcc does not support this either, and the only way to get such an object is with __attribute__((aligned)) or generic vectors; it can't be done in a standard-conforming program, or with Altivec. So I think disabling it is OK.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48188 91177308-0d34-0410-b5e6-96231b3b80d8
