2012-01-23Simplify some NEON assembly pseudo definitions.Jim Grosbach
Let the generic token alias definitions handle the data subtype suffices. We don't need explicit versions for each. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148718 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-20More dead code removal (using -Wunreachable-code)David Blaikie
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148578 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-20NEON use vmov.i32 to splat some f32 values into vectors.Jim Grosbach
For bit patterns that aren't representable using the 8-bit floating point representation for vmov.f32, but are representable via vmov.i32, treat the .f32 syntax as an alias. Most importantly, this covers the case 'vmov.f32 Vd, #0.0'. rdar://10616677 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148556 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Thumb2 alternate syntax for LDR(literal) and friends.Jim Grosbach
Explicit pc-relative syntax. For example, "ldrb r2, [pc, #-22]". rdar://10250964 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148432 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-16Removing unused default switch cases in switches over enums that already ↵David Blaikie
account for all enumeration values explicitly. (This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148262 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-03Fix malformed assert.Matt Beaumont-Gay
If anybody has strong feelings about 'default: assert(0 && "blah")' vs 'default: llvm_unreachable("blah")', feel free to regularize the instances of each in this file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147459 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-22ARM assembler should accept shift-by-zero for any shifted-immediate operand.Jim Grosbach
Just treat it as-if the shift wasn't there at all. 'as' compatibility. rdar://10604767 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147153 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-21ARM asm parser should be more lenient w/ .thumb_func directive.Jim Grosbach
Rather than require the symbol to be explicitly an argument of the directive, allow it to look ahead and grab the symbol from the next non-whitespace line. rdar://10611140 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147100 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-21Thumb2 assembly parsing of 'mov rd, rn, rrx'.Jim Grosbach
Maps to the RRX instruction. Missed this case earlier. rdar://10615373 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147096 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20ARM assembly shifts by zero should be plain 'mov' instructions.Jim Grosbach
"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's not strictly legal UAL syntax. It's a common extension and the friendly thing to do. rdar://10604663 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146937 91177308-0d34-0410-b5e6-96231b3b80d8
