Evan Cheng cb0f06e05c Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this: ... addl $12, %esp popl %esi popl %edi popl %ebx popl %ebp jmpl *__Block_deallocator-L1$pb(%esi) # TAILCALL The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class. The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99455 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-25 00:10:31 +00:00
