crt files and statically linked libgcc objects cause false positives
|
||
|
|
in annobin coverage, so we add the assembler flag to generate notes
|
||
|
|
for them.
|
||
|
|
|
||
|
|
The patch also adds notes to libgcc_s.so, but this is harmless because
|
||
|
|
these notes only confer that there is no other annobin markup.
