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:

"boolify" pointers, generating really awful code because getting the pointer
value requires a load itself. Before:
_foo:
movb $1, _X.b
ret
_get:
xorl %ecx, %ecx
movb _X.b, %al
testb %al, %al
movl $_Y, %eax
cmove %ecx, %eax
ret
With the xform disabled:
_foo:
movl $_Y, _X
ret
_get:
movl _X, %eax
ret

While thinking about the one-definition-rule and trying2009-03-06T10:21:56ZDuncan Sandsbaldrick@free.fr2009-03-06T10:21:56Zurn:sha1:fc5940d2a09a795e683ae86b237d6f55fb3551d4
to find a tiny mouse hole to squeeze through, it struck
me that globals without a name can be considered internal
since they can't be referenced from outside the current
module. This patch makes GlobalOpt give them internal
linkage. Also done for aliases even though they always
have names, since in my opinion anonymous aliases should
be allowed for consistency with global variables and
functions. So if that happens one day, this code is ready!

GlobalOpt only process non constant local GVs while optimizing global vars.2009-03-05T18:12:02ZDevang Pateldpatel@apple.com2009-03-05T18:12:02Zurn:sha1:504960067233f271884c23869e81272918ad2883
If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B.
In other words, debug info should not interfere in removal of unused GV.
