perf annotate: Support full source file paths for srcline fix
The --full-paths option did not show the full source file paths in the 'perf
annotate' tool, because the value of the option was not propagated into the
related functions.
With this patch the value of the --full-paths option is known to the function
that composes the srcline string, so it prints the full path when necessary.
Committer Note:
This affects annotate when the --print-line option is used:
# perf annotate -h 2>&1 | grep print-line
-l, --print-line print matching source lines (may be slow)
Looking just at the lines that should be affected by this change:
Before:
# perf annotate --print-line --full-paths --stdio fput | grep '\.[ch]:[0-9]\+'
94.44 atomic64_64.h:114
5.56 file_table.c:265
file_table.c:265 5.56 : ffffffff81219a00: callq ffffffff81769360 <__fentry__>
atomic64_64.h:114 94.44 : ffffffff81219a05: lock decq 0x38(%rdi)
After:
# perf annotate --print-line --full-paths --stdio fput | grep '\.[ch]:[0-9]\+'
94.44 /home/git/linux/arch/x86/include/asm/atomic64_64.h:114
5.56 /home/git/linux/fs/file_table.c:265
/home/git/linux/fs/file_table.c:265 5.56 : ffffffff81219a00: callq ffffffff81769360 <__fentry__>
