2009-07-08- Add some NEON ld / st instruction static encoding.Evan Cheng
- Make bits 25-27 for ldrh, etc. explicitly zero. Previously only the JIT uses the encoding information and it's assuming anything not specified to be zero. Making them explicit so the disassembler is happy. Patch by Sean Callanan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75065 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Change how so_imm and t2_so_imm are handled. At instruction selection time, ↵Evan Cheng
the immediates are no longer encoded in the imm8 + rot format, that are left as it is. The encoding is now done in ams printing and code emission time instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75048 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Recommit r74952 with a bug fix:Bill Wendling
DWARF requires frame moves be specified at specific times. If you have a prologue like this: __Z3fooi: Leh_func_begin1: LBB1_0: ## entry pushl %ebp Llabel1: movl %esp, %ebp Llabel2: pushl %esi Llabel3: subl $20, %esp call "L1$pb" "L1$pb": popl %esi The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp, %ebp" makes %ebp the new stack frame register, so that needs to be specified in DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs to be specified in DWARF. Before, all of this logic was in one method. This didn't work too well, because as you can see there are multiple FDE line entries that need to be created. This fix creates the "MachineMove" objects directly when they're needed; instead of waiting until the end, and losing information. There is some ugliness where we generate code like this: LBB22_0: ## entry pushl %ebp Llabel280: movl %esp, %ebp Llabel281: Llabel284: pushl %ebp <---------- pushl %ebx pushl %edi pushl %esi Llabel282: subl $328, %esp Notice the extra "pushl %ebp". If we generate a "machine move" instruction in the FDE for that pushl, the linker may get very confused about what value %ebp should have when exitting the function. I.e., it'll give it the value %esp instead of the %ebp value from the first "pushl". Not to mention that, in this case, %ebp isn't modified in the function (that's a separate bug). I put a small hack in to get it to work. It might be the only solution, but should be revisited once the above case is fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75047 91177308-0d34-0410-b5e6-96231b3b80d8
