Bug ID: 38137
Summary: Inconsistency in printing Windows filespecs
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: MC
Assignee: unassignedb...@nondot.org
Reporter: paul_robin...@playstation.sony.com

llvm/test/MC/ELF/debug-prefix-map.s was updated in r336793 to test
a case with absolute paths.
The change used the usual {{/|\\}} regex to try to accommodate Windows
path separators, however it still failed:
http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/18383
The relevant detail is:
# command stderr:
C:\ps4-buildslave2\llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast\llvm.src\test\MC\ELF\debug-prefix-map.s:23:13:
error: expected string not found in input
// MAP_ABS: DW_AT_name [DW_FORM_string] ("{{/|\\}}src_root{{(/|\\)}}src.s")
^
<stdin>:1:1: note: scanning from here
out.o: file format ELF64-x86-64
^
<stdin>:10:2: note: possible intended match here
DW_AT_name [DW_FORM_string] ("/src_root\\src.s")
^
Note that the backslash is doubled, which the regex can't accommodate.
As a temporary quick fix I added a "+" suffix to the patterns to allow
multiple separators. However, really we shouldn't be doubling the
backslash. We need to track down why that's happening and take care of it.
