Chris Lattner 145c532e68 Enhance SRoA to be more aggressive about scalarization of aggregate allocas ... that have PHI or select uses of their element pointers. This can often happen when instcombine sinks two loads into a successor, inserting a phi or select. With this patch, we can scalarize the alloca, but the pinned elements are not yet promoted. This is still a win for large aggregates where only one element is used. This fixes rdar://8904039 and part of rdar://7339113 (poor codegen on stringswitch). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124070 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-23 08:27:54 +00:00

Support	Clang was not parsing target triples involving EABI and was generating wrong IR (wrong PCS) and passing the wrong information down llc via the target-triple printed in IR. I've fixed this by adding the parsing of EABI into LLVM's Triple class and using it to choose the correct PCS in Clang's Tools. A Clang patch is on its way to use this infrastructure.	2011-01-21 18:25:47 +00:00
