Bug ID: 15938
Summary: --start/--end-lib renders --print-map (Archive member
included because of...) useless
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: gold
Assignee: ian at airs dot com
Reporter: ppluzhnikov at google dot com
CC: ccoutant at google dot com
When debugging linking problems, it is often useful to understand what caused a
particular file (foo.o below) to be pulled out of archive.
The --print-map output has a section which answers that, e.g.:
Archive member included because of file (symbol)
./libfoo.a(foo.o) main.o (foo)
Gold (GNU gold (GNU Binutils 2.23.52.20130907) 1.11) does not print that info
when using --start-lib foo.o --end-lib
Repro steps:
cat main.c
int foo();
int main() { return foo(); }
cat foo.c
int foo() { return 42; }
gcc -c foo.c main.c
ar ruv libfoo.a foo.o
# shows why foo.o was selected:
gcc main.o -L. -lfoo -Wl,--print-map
# does *not* show why foo.o was selected:
gcc main.o -Wl,--start-lib foo.o --Wl,--end-lib -Wl,--print-map
