Jeremy Morse 6df259fb43 [InstrRef][X86] Drop debug instruction numbers from x87 instructions ... Avoid a crash when using instruction referencing if x87 floating point instructions are used. These instructions are significantly mutated when they're rewritten from referring to registers, to referring to floating-point-stack positions. As a result, their operands are re-ordered, and (InstrRef) LiveDebugValues asserts when it sees a DBG_INSTR_REF referring to a non-reg non-def register operand. To fix this, drop the instruction numbers, and thus variable locations. This patch adds a helper utility do do that. Dropping the variable locations is sub-optimal, but applying DBG_VALUEs to the $fp0 and similar registers is dropped on emission too. It seems we've never done well at describing variables that live in x87 registers, at all. Differential Revision: https://reviews.llvm.org/D105657		2021-07-19 15:08:27 +01:00
