Resubmit r301309: [DebugInfo][X86] Fix handling of DBG_VALUE's in post-RA scheduler. This patch reapplies r301309 with the fix to the MIR test to fix the assertion triggered by r301309. Had trimmed a little bit too much from the MIR! llvm-svn: 301317

# RUN: llc -mtriple=x86_64-unknown-unknown -mcpu=btver2 -run-pass=post-RA-sched -o - %s | FileCheck %s
# Test that multiple DBG_VALUE's following an instruction whose register needs
# to be changed during the post-RA scheduler pass are updated correctly.
# Test case was derived from the output from the following command and
# the source code below:
#
# clang -S -emit-llvm -target x86_64 -march=btver2 -O2 -g -o - <srcfile> |
# llc -stop-before=post-RA-sched -o -
#
# Source code reduced from the original 8MB source file:
#
# struct a;
# class b {
# public:
# a *c = ap;
# unsigned *d() { return (unsigned *)c; }
# a *ap;
# };
# enum { e = 2 };
# template <typename f> f *g(f *h, f *i) {
# long j = long(i), k = -!h;
# return reinterpret_cast<f *>(long(h) | k & j);
# }
# class l {

Parse and print DIExpressions inline to ease IR and MIR testing Summary: Most DIExpressions are empty or very simple. When they are complex, they tend to be unique, so checking them inline is reasonable. This also avoids the need for CodeGen passes to append to the llvm.dbg.mir named md node. See also PR22780, for making DIExpression not be an MDNode.

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

Resubmit r301309: [DebugInfo][X86] Fix handling of DBG_VALUE's in post-RA scheduler. This patch reapplies r301309 with the fix to the MIR test to fix the assertion triggered by r301309. Had trimmed a little bit too much from the MIR! llvm-svn: 301317
