* Implement more support for fp-to-i128 and i128-to-fp conversions. Dan Gohman2008-03-102-80/+133

* Disable prolog code that aligns the stack when aDale Johannesen2008-03-101-7/+17
| | | | | | | | | | | | | | | | 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
