All cases I've seen involved float softening in the type legalizer, and this could be perhaps be fixed there, but it's better not to generate things differently in the first place. 7797940 (6/29/2010..7/15/2010). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108484 91177308-0d34-0410-b5e6-96231b3b80d8

* Handle code gen for the unreachable instruction if it's the only instruction inBill Wendling2010-07-154-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the function. We'll just turn it into a "trap" instruction instead. The problem with not handling this is that it might generate a prologue without the equivalent epilogue to go with it: $ cat t.ll define void @foo() { entry: unreachable } $ llc -o - t.ll -relocation-model=pic -disable-fp-elim -unwind-tables .section __TEXT,__text,regular,pure_instructions .globl _foo .align 4, 0x90 _foo: ## @foo Leh_func_begin0: ## BB#0: ## %entry pushq %rbp Ltmp0: movq %rsp, %rbp Ltmp1: Leh_func_end0: ... The unwind tables then have bad data in them causing all sorts of problems.

| | | | | | | | | | | | | to keep "Text" in sync with the "pure instructions" section attribute. Lack of this attribute was preventing the assembler from emitting multibyte noops instructions for templates (and inlines, and other coalesced stuff) and was causing the assembler to mismatch .o files.

* Don't merge uses when they are targetting fixup sites withDan Gohman2010-07-151-1/+20
| | | | | | | | | | | | | | different widths. In a use with a narrower fixup, formulae may be wider than the fixup, in which case the high bits aren't necessarily meaningful, so it isn't safe to reuse them for uses with wider fixups. This fixes PR7618, though the testcase is too large for a reasonable regression test, since it heavily dependes on hitting LSR's heuristics in a certain way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108455 91177308-0d34-0410-b5e6-96231b3b80d8
