* Use subclassing to print lane-like immediates (w/o hash) eliminatingAnton Korobeynikov2009-08-085-32/+37
| | | | | | 'no_hash' modifier. Hopefully this will make Daniel happy :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78514 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/AsmMatcher: Tweak string matcher.Daniel Dunbar2009-08-081-26/+28
| | | | | | | | | | | | - Track whether we need to insert an explicit 'break'. - Invert conditional when matching a single prefix to reduce nesting/bracing/breaking. - wc -l of X86GenAsmMatcher.inc decreased by 10%. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78513 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | 2. Move section switch printing to MCSection virtual method which takes a TAI. This eliminates textual formatting stuff from TLOF. 3.

* Clean out per-function data after the machine code verifier is done with it.Jakob Stoklund Olesen2009-08-081-0/+8
| | | | | | | | | | | | | | | Also don't dereference old pointers after they have been deleted causing random crashes when enabling the machine code verifier. Ahem... I have not included a test case for the crash. It hapened when enabling the verifier on CodeGen/X86/2009-08-06-branchfolder-crash.ll. The crash depends on an MBB being allocated at the same address as a previously deleted MBB. I don't think that can be reproduced reliably. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78472 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | mistaken commit r77904. Now there is no special treatment of instructions that redefine part of a super-register. Instead, the super-register is marked with <imp-use,kill> and <imp-def>. For instance, from LowerSubregs on ARM: subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1<undef>, %D1<kill>, 5 subreg: %D2<def> = FCPYD %D1<kill>, 14, %reg0, %Q1<imp-def> subreg: CONVERTING: %Q1<def> = INSERT_SUBREG %Q1, %D0<kill>, 6 subreg: %D3<def> = FCPYD %D0<kill>, 14, %reg0, %Q1<imp-use,kill>, %Q1<imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78466 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | Verify that early clobber registers and their aliases are not used. All changes to RegsAvailable are now done as a transaction so the order of operands makes no difference.

* llvm-mc/AsmMatcher: Improve match code.Daniel Dunbar2009-08-084-131/+319
| | | | | | | | | | | | | | | - This doesn't actually improve the algorithm (its still linear), but the generated (match) code is now fairly compact and table driven. Still need a generic string matcher. - The table still needs to be compressed, this is quite simple to do and should shrink it to under 16k. - This also simplifies and restructures the code to make the match classes more explicit, in anticipation of resolving ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78461 91177308-0d34-0410-b5e6-96231b3b80d8
