* Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.Bob Wilson2010-03-1610-38/+10

In the testcase, we generate references to the two bb's when codegen'ing the first function: _test1: ## @test1 leaq Ltmp0(%rip), %rax .. leaq Ltmp1(%rip), %rax Then continue to codegen the second function where the blocks get merged. We're now smart enough to emit both labels, producing this code: _test_fun: ## @test_fun ## BB#0: ## %entry Ltmp1: ## Block address taken Ltmp0: ## BB#1: ## %ret movl $-1, %eax ret Rejoice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98595 91177308-0d34-0410-b5e6-96231b3b80d8
* MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.Daniel Dunbar2010-03-1510-134/+124
| | | | | | | - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue. - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98592 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | changing the primary datastructure from being a "std::vector<unsigned char>" to being a new TypeSet class that actually has (gasp) invariants! This changes more things than I remember, but one major innovation here is that it enforces that named input values agree in type with their output values. This also eliminates code that transparently assumes (in some cases) that SDNodeXForm input/output types are the same, because this is wrong in many case. This also eliminates a bug which caused a lot of ambiguous patterns to go undetected, where a register class would sometimes pick the first possible type, causing an ambiguous pattern to get arbitrary results. With all the recent target changes, this causes no functionality change! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98534 91177308-0d34-0410-b5e6-96231b3b80d8
