Generalize LCSSA to handle loops with exits with predecessors outside2009-11-09T18:28:24ZDan Gohmangohman@apple.com2009-11-09T18:28:24Zurn:sha1:f6572d0aa2abb87d34afcca3e3bec89e1613b8ec
the loop. This is needed because with indirectbr it may not be possible
for LoopSimplify to guarantee that all loop exit predecessors are
inside the loop. This fixes PR5437.
LCCSA no longer actually requires LoopSimplify form, but for now it
must still have the dependency because the PassManager doesn't know
how to schedule LoopSimplify otherwise.

Move the dominator verification code out of special code embedded within2009-09-28T00:27:48ZDan Gohmangohman@apple.com2009-09-28T00:27:48Zurn:sha1:9450b0e1a6154192ca597ad27f8eb6e6e807f7a4
the PassManager code into a regular verifyAnalysis method.
Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.

output so that grep lines in the tests don't unintentionally match
strings in the input filename.

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:
