* Revert 103911; it broke a test that expects bitconvertDale Johannesen2010-05-161-4/+0
| | | | | | | | | | | <1xi64> -> i64 to work in MMX registers on hosts where -no-sse is the default (not mine). The right thing is to accept this and make i64->f64 conversions go through memory, but I don't have time right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103914 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix uint64->{float, double} conversion to do rounding correctly in 32-bit.Dale Johannesen2010-05-151-23/+59
| | | | | | | | | | | | | | | | | | | The implementation in LegalizeIntegerTypes to handle this as sint64->float + appropriate power of 2 is subject to double rounding, considered incorrect by numerics people. Use this implementation only when it is safe. This leads to using library calls in some cases that produced inline code before, but it's correct now. (EVTToAPFloatSemantics belongs somewhere else, any suggestions?) Add a correctly rounding (though not particularly fast) conversion that uses X87 80-bit computations for x86-32. 7885399, 5901940. This shows up in gcc.c-torture/execute/ieee/rbug.c in the gcc testsuite on some platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103883 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | instructions which have no direct register usage. Darwin 'as' accepts: add $0, (%rax) but rejects mov $0, (%rax) for example. Given that, only accept suffix matches which match exactly one form. We still need to emit nice diagnostics for failures... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103015 91177308-0d34-0410-b5e6-96231b3b80d8
* MC/X86: Add "support" for matching ATT style mnemonic prefixes.Daniel Dunbar2010-05-042-4/+66
| | | | | | | | | | | | | | | | | - The idea is that when a match fails, we just try to match each of +'b', +'w', +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept it. If all match, we assume it is width generic, and take the 'l' form. - This would be a horrible hack, if it weren't so simple. Therefore it is an elegant solution! Chris gets the credit for this particular elegant solution. :) - Next step to making this more robust is to have the X86 matcher generate the mnemonic prefix information. Ideally we would also compute up-front exactly which mnemonic to attempt to match, but this may require more custom code in the matcher than is really worth it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103012 91177308-0d34-0410-b5e6-96231b3b80d8
