Summary: D76801 caused some regressions in debuginfo compatibility by changing how certain functions were named. For CodeView we try to mirror MSVC exactly: this was fixed in a549c0d00486 For DWARF the situation is murkier. Per David Blaikie: > In general DWARF doesn't specify this at all. > [...] > This isn't the only naming divergence between GCC and Clang Nevertheless, including the space seems to provide better compatibility with GCC and GDB. E.g. cpexprs.cc in the GDB testsuite requires this formatting. And there was no particular desire to change the printing of names in debug info in the first place (just in diagnostics and other more user-facing text).
