2011-03-25Instruction formats of SWP/SWPB were changed from LdStExFrm to MiscFrm. ↵Johnny Chen
Modify the disassembler to handle that. rdar://problem/9184053 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128285 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-25Emit less labels for debug info and stop emitting .loc directives for ↵Jakob Stoklund Olesen
DBG_VALUEs. The .dot directives don't need labels, that is a leftover from when we created line number info manually. Instructions following a DBG_VALUE can share its label since the DBG_VALUE doesn't produce any code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128284 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-25Fix for -pre-RA-sched=source.Andrew Trick
Yet another case of unchecked NULL node (for physreg copy). May fix PR9509. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128266 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-25Ignore special ARM allocation hints for unexpected register classes.Jakob Stoklund Olesen
Add an assertion to linear scan to prevent it from allocating registers outside the register class. <rdar://problem/9183021> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128254 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-25Modify the wrong logic in the assert of DisassembleThumb2LdStDual() (the ↵Johnny Chen
register classes were changed), modify the comment to be up-to-date, and add a test case for A8.6.66 LDRD (immediate) Encoding T1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128252 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-25delegate the disassembly of t2ADR to the more generic t2ADDri12/t2SUBri12 ↵Johnny Chen
instructions, and add a test case for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128249 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24The opcode names ("tLDM", "tLDM_UPD") used for conflict resolution have been ↵Johnny Chen
stale since the change to ("tLDMIA", "tLDMIA_UPD"). Update the conflict resolution code and add test cases for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128247 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24The ARM disassembler was confused with the 16-bit tSTMIA instruction.Johnny Chen
According to A8.6.189 STM/STMIA/STMEA (Encoding T1), there's only tSTMIA_UPD available. Ignore tSTMIA for the decoder emitter and add a test case for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128246 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-24T2 Load/Store Multiple:Johnny Chen
These instructions were changed to not embed the addressing mode within the MC instructions We also need to update the corresponding assert stmt. Also add a test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128240 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-24Remove these two test files as they cause llvm-i686-linux-vg_leak build to ↵Johnny Chen
fail 'test-llvm'. These two are test cases which should result in 'invalid instruction encoding' from running llvm-mc -disassemble. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128235 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24ADR was added with the wrong encoding for inst{24-21}, and the ARM decoder ↵Johnny Chen
was fooled. Set the encoding bits to {0,?,?,0}, not 0. Plus delegate the disassembly of ADR to the more generic ADDri/SUBri instructions, and add a test case for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128234 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24Keep track of directory namd and fIx regression caused by Rafael's patch ↵Devang Patel
r119613. A better approach would be to move source id handling inside MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128233 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24Clean up assembly statement separator support.Jim Grosbach
The MC asm lexer wasn't honoring a non-default (anything but ';') statement separator. Fix that, and generalize a bit to support multi-character statement separators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-24The r118201 added support for VORR (immediate). Update ↵Johnny Chen
ARMDisassemblerCore.cpp to disassemble the VORRiv*i* instructions properly within the DisassembleN1RegModImmFrm() function. Add a test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128226 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-24Nasty bug in ARMBaseInstrInfo::produceSameValue(). The MachineConstantPoolEntryEvan Cheng
entries being compared may not be ARMConstantPoolValue. Without checking whether they are ARMConstantPoolValue first, and if the stars and moons are aligned properly, the equality test may return true (when the first few words of two Constants' values happen to be identical) and very bad things can happen. rdar://9125354 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128203 91177308-0d34-0410-b5e6-96231b3b80d8
