The next step in moving to toplevel libgcc is the shared libgcc_s (SHLIB_*) support. It has already been done for Darwin, Solaris, IRIX, and Tru64 UNIX, so here follows the rest. Apart from the obvious stuff (move SHLIB_* and corresponding version scripts and support files from gcc to libgcc), I've done a lot of cleanup and simplification which needs testing: * At the moment, SHLIB_LINK is used in gcc/Makefile.in and the various Make-lang.in fragments to check if the target supports a shared libgcc_s. I've introduced gcc/config/t-slibgcc (from t-slibgcc-dummy) for this, which sets SHLIB = true, adding that fragment to all targets in config.gcc that do. There may be a better way to handle this. * Several of the SHLIB_* variables were (almost) identical copies of each other, or of previous versions. I've tried to remove as much duplication as possible. In order that one can easily see what's going on, all the SHLIB_* support now lives in t-slibgcc* files in libgcc/config. * Some OSes were changed in particular: ** AIX: Both t-aix43 and t-aix52 SHLIB_* variables now live in rs6000/t-slibgcc-aix. They were identical except that the t-aix52 variant had been updated for cross-compilation. I haven't changed them to allow use of t-slibgcc, but that could perhaps be done as a followup. ** HP-UX: After editing the PA and IA-64 HP-UX SHLIB_* variables into a form to allow comparison with t-slibgcc, it turned out that the differences are actually minimal. I only needed to introduce INSTALL_SHLIB to allow for the install -m 555 of the shared libgcc_s only needed on HP-UX. ** VMS: Alpha and IA-64 VMS support could again be unified into t-slibgcc-vms. There are two noteworthy changes: BASEVER_c isn't available outside of gcc, so I need to parse $(CC) --version output instead. While alpha/t-vms already extracted symbol information with objdump --syms, ia64/t-vms still used a hardcoded list (ia64/vms_symvec_libgcc_s.opt). Since it has the comment `It would be better to auto-generate this file.', I've omitted it, hoping that the alpha procedure also works on ia64. This obviously needs to be tested. ** Windows: While the windows code hasn't been touched apart from the move, the various t-* fragments are so interdependent that I could easily have made a mistake. * In libgcc/config.host, I've checked that all targets that set tmake_file in target-specific clauses append to tmake_file to keep the OS-specific defaults, adding comments in the few cases where that's not possible. In a couple of cases, I had to adapt (instead of just moving) the SHLIB_MAPFILES settings to allow for that. I've added comments where necessary. * There was considerable variety in the naming of the version scripts. To reduce it, I've standardized on a libgcc-*.ver naming scheme, mostly libgcc-glibc.ver for Linux targets. * The test for sjlj exceptions was already (almost) duplicated 3 times in libgo (for C), libjava (for C++), and libobjc (for Objective-C). I've created just another copy from the libgo variant, but it would be better to centralize this. * There's another issue I haven't attacked yet: while currently libgcc/Makefile.in performs a couple of substitions on SHLIB_* variables, this shouldn't be necessary any longer: @multilib_dir@ $(MULTIDIR) @multilib_flags@ $(CFLAGS) -B./ @shlib_base_name@ libgcc_s @shlib_map_file@ $(mapfile) @shlib_objs@ $(objects) @shlib_slibdir@ $(shlib_slibdir) @shlib_slibdir_qual@ $(MULTIOSSUBDIR) There should be a better way to handle this. The patch has been bootstrapped without regressions on i386-pc-solaris2.10 and x86_64-unknown-linux-gnu. On Linux/x86_64, I've verified that libgcc_s.so.1 versioning is unchanged with a script derived from libstdc++-v3/scripts/extract_symvers.in. Bootstraps on i386-apple-darwin9.8.0 and powerpc-apple-darwin9.8.0 are in progress and already well into building the target libraries. Earlier versions of the patch have also been bootstrapped on alpha-dec-osf5.1b and mips-sgi-irix6.5, but there's not much point in repeating that now since those have alreay been migrated on their own. Could affected OS port/target maintainers please give the patch a try? Thanks. Rainer 2011-07-25 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gcc: * Makefile.in (slibdir): Remove, don't export.
