Bill Wendling 991234752d Handle code gen for the unreachable instruction if it's the only instruction in ... 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. Fixes <rdar://problem/8096481>. llvm-svn: 108473		2010-07-15 23:32:40 +00:00
