Share gcc work directories
This patched is derived from Richard, make gcc use the shared source
directory during the different building:
1) Make gcc-cross, gcc-cross-initial, gcc-cross-intermediate and
gcc-runtime share the same source directory.
2) The source directory is ${TMPDIR}/work-shared/gcc-${PV}, for example:
tmp/work-shared/gcc-4.5.1
3) Fix do_clean to clean the shared source directory and stamps
4) gcc uses sed and creates config files against ${S} which means the
directory should not be shared. Change the way to make it work:
* The configure option --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS}
can replace the sed command, see the code in configure:
if test "x$with_headers" != x; then
glibc_header_dir=$with_headers
This has the same effect as the sed command:
sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ...
so add the --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} to
gcc-configure-cross.inc( not add to gcc-configure-common.inc, since
not all the gcc building need this, the one which has its own do_configure
doesn't need it).
* Move t-oe from ${T} to ${B}/gcc, so that the patched Makefile.in
can read it easily, please see the commit for gcc-4.5.1 and
gcc-4.6.0.
* Use the defaults.h in ${B}/gcc instead of ${S}/gcc, and the patched
configure.ac(configure) can read it correctly, please see the
commit for gcc-4.5.1 and gcc-4.6.0.
* The gcc-crosssdk.inc used sed to edit ${S}/config/*/linux*.h
to change the GLIBC_DYNAMIC_LINKER, which made the source
incompatible. To make the source compatible:
- Use:
sed -i ${S}/gcc/config/*/linux*.h -e \
's#\(GLIBC_DYNAMIC_LINKER[^ ]*\)\( *"/lib.*\)#\1 SYSTEMLIBS_DIR\2#'
so entries in the files that look like:
#define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2"
would become
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
and we define SYSTEMLIBS_DIR in defaults.h.
NOTE:
#define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2")
doesn't work in in the following define:
#define LINUX_DYNAMIC_LINKER \
CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER)
so use
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
5) Add do_configure_prepend to gcc-configure-common.inc and remove the
one in gcc-crosssdk.inc, this makes it easy to share the source,
otherwise we need do extra changes in gcc-configure-sdk.inc.
6) Use "cat > file <_EOF" to replace the "echo > file"
