Bug ID: 27280
Summary: md5 DWARF v5 additions require -gdwarf-5
Product: binutils
Version: 2.35.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: ndesaulniers at google dot com

Target Milestone: ---
$ echo '.file 1 "filename" md5 0x7a0b65214090b6693bd1dc24dd248245' |
binutils-gdb/gas/as -
{standard input}: Assembler messages:
{standard input}:1: Error: junk at end of line, first unrecognized character is
`m'
$ echo '.file 1 "filename" md5 0x7a0b65214090b6693bd1dc24dd248245' |
binutils-gdb/gas/as -gdwarf-5 -
Support for these md5 hashes was addressed in
https://sourceware.org/bugzilla/show_bug.cgi?id=25611, but they still require
-gdwarf-5.
-gdwarf-5 is not required for `.file 0` in
https://sourceware.org/bugzilla/show_bug.cgi?id=27195. The same approach
should be used to avoid requiring `-gdwarf-5` to be passed explicitly, since
the compiler (clang -no-integrated-as) will produce these checksums when
`-gdwarf-5` is used and the compiler is used as the driver.
