When extending a memset range past the front, set the alignment of the
memset region to the alignment of the new start address.

Split the Add, Sub, and Mul instruction opcodes into separate2009-06-04T22:49:04ZDan Gohmangohman@apple.com2009-06-04T22:49:04Zurn:sha1:ae3a0be92e33bc716722aa600983fc1535acb122
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:

Rename the last test with .llx extension to .ll, resolve duplicate test by renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too.2008-05-20T19:52:04ZGabor Greifggreif@gmail.com2008-05-20T19:52:04Zurn:sha1:722243bd402aaed698a279cb323cf37554befd53

Fix a bug in memcpyopt where the memcpy-memcpy transform was never being applied because 2008-04-29T21:26:06ZOwen Andersonresistor@mac.com2008-04-29T21:26:06Zurn:sha1:9dcace3cafb4da5c3d94f3b89e54ea0d7164a286
we were checking for it in the wrong order. This caused a miscompilation because the
return slot optimization assumes that the call it is dealing with is NOT a memcpy.
