I noticed that if one is compiling and linking in one step (no
-c
flag tocc
), then the hardening ld flags are passed twice. I'd think either they'd just be passed to ld, or they'd be passed tocc
and guarded inld-wrapper
underLDFLAGS_SET
. Is this intended?I am soon going to make a PR for splitting a
binutils-wrapper
derivation, out of cc-wrapper, and this makes it a bit unclear how the division of labor for hardening ought to work.aff1f4a
