2013-02-13X86: Disable generation of rep;movsl when %esi is used as a base pointer.Benjamin Kramer
This happens when there is both stack realignment and a dynamic alloca in the function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the base pointer and the next register spill will write into oblivion. Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas and freebsd a 4 byte stack alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175057 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-12[ms-inline asm] Add support for lexing binary integers with a [bB] suffix.Chad Rosier
This is complicated by backward labels (e.g., 0b can be both a backward label and a binary zero). The current implementation assumes [0-9]b is always a label and thus it's possible for 0b and 1b to not be interpreted correctly for ms-style inline assembly. However, this is relatively simple to fix in the inline assembly (i.e., drop the [bB]). This patch also limits backward labels to [0-9]b, so that only 0b and 1b are ambiguous.

2013-02-12This CL supersedes the previous 2 outstanding CLs.Derek Schuff
1) Remove the ABIVerifyErrors class since it was just a wrapper with no real functionality. Replace with a simple string ostream for now. If in the future we want to have more intelligent error handling, we can come up with something that does what we actually decide we want. 2) When printing type errors in initializers, just print the Type that was invalid, rather than the whole initializer. This is implemented by having checkTypesInValue return the Type that was invalid, rather than just a boolean. 3) Check the type of each instruction (this is just to make sure it works from the function pass). Do not, however, make the passes dependent as in the previous CL (function passes cannot depend on module passes, but there are no checks for this, and opt does not enforce the dependence, and when llc tries to enforce it, very bad things happen) 2) Style cleanup to match LLVM style. Sorry for the multiple changes in one CL, hopefully it's still small enough to be reviewable. BUG= Review URL: https://codereview.chromium.org/12224109

2013-02-12[NVPTX] Disable vector registersJustin Holewinski
Vectors were being manually scalarized by the backend. Instead, let the target-independent code do all of the work. The manual scalarization was from a time before good target-independent support for scalarization in LLVM. However, this forces us to specially-handle vector loads and stores, which we can turn into PTX instructions that produce/consume multiple operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174968 91177308-0d34-0410-b5e6-96231b3b80d8
