Bug ID: 17448
Summary: gold doesn't work with --dynamic-list=<(echo '...')
construct (non-seekable pipe input)
Product: binutils
Version: 2.24
Status: NEW
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at google dot com
Reporter: martinrb at google dot com
CC: ian at airs dot com
The self-explanatory bash snippet below shows that --dynamic-list must be a
"real" file and that gold's error message is misleading and contains
implementation details of the file parser (what's $end?; what do you mean, you
were looking for '{' in column 1?? It's right there!). Whereas bfd ld works
correctly.
$ for ld in bfd gold; do echo -- $ld --; gcc --use-ld=$ld
-Wl,--dynamic-list=<(echo '{ main; };') main.c && nm -D a.out; done
-- bfd --
w __gmon_start__
U __libc_start_main

/usr/bin/ld.gold: error: /proc/self/fd/11:1:1: syntax error, unexpected $end,
expecting '{'
