New Revision: 296921
URL: https://svnweb.freebsd.org/changeset/base/296921
Log:
Partially revert r266227 and stop stripping paths in ldscripts.
Specifically this fixes /usr/lib/libc.so stripping the paths to the
libraries. The reason for this in r266227 was both likely because ld(1) did
not fully respect --sysroot until r291226 and because of the lib32
build. The lib32 build does not use --sysroot into the /usr/lib32 path,
rather it only uses -L and -B into the /usr/lib32 path and --sysroot
into the normal (64bit) /usr/lib. The _LDSCRIPTROOT was added with
the ldscript support in bsd.lib.mk so that it builds a 32-bit-sysrooted pathed
ldscript in the object directory and then installs a normal unprefixed
version in installworld. This commit also fixes the rebuild during
install which was broken in r266227. This commit would break DIRDEPS_BUILD
build of lib32 but it does not currently have a way to build it anyhow.
For example, before this change we had in /usr/lib/libc.so:
GROUP ( libc.so.7 libc_nonshared.a libssp_nonshared.a )
Now it is restored to pre-r266227:
GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a
/usr/lib/libssp_nonshared.a )
The motivation for this is in testing of lld.
From emaste:
lld does not have built-in search paths (e.g. /lib, /usr/lib) and relies on
-L arguments passed by the caller. As the linker is nearly always invoked
from the clang driver this is fine other than the fact that /usr/lib/libc.so
is an ldscript that refers to libc.so.7 which is in /lib, not /usr/lib.
