How does this interact with rm_work?
The rm_work does not delete anything in work-shared, I think this is fine,
otherwise the source can not be shared.
it also limits the possibility of patching the sources differently if need be.
Can it do that easily suppose gcc intermediate needs a patch for a given arch
Yes, the source must be the same if they want to use the shared source. When we
want to patch the source, I think proper way is try to patch them general(not
only for a given arch).
and others don't then can it make gcc cross intermediate not use shared source
Yes, when the following variables are not defined(or defined to other value)
for gcc intermediate, then it would not use the shared source.
S = "${TMPDIR}/work-shared/gcc-${PV}/gcc-${PV}"
B = "${WORKDIR}/gcc-${PV}/build.${HOST_SYS}.${TARGET_SYS}"
# SS means Shared Stamps directory
SS = "${TMPDIR}/stamps/work-shared/gcc-${PV}"
do_fetch[stamp-base] = "${SS}"
do_unpack[stamp-base] = "${SS}"
do_patch[stamp-base] = "${SS}"
# SW means Shared Work directory
SW = "${TMPDIR}/work-shared/gcc-${PV}"
WORKDIR_task-unpack = "${SW}"
WORKDIR_task-patch = "${SW}"
