2022-10-11Generic configury support for shared libs on VxWorksOlivier Hainque1-0/+24
This change adds the configury bits to activate the build of shared libs on VxWorks ports configured with --enable-shared, for libraries variants where this is generally supported (rtp, code model !large - currently not compatible with -fPIC). Set lt_cv_deplibs_check_method in libtool.m4, so the build of libraries know how to establish dependencies. This is useful in configurations such as aarch64 where proper support of LSE relies on accurate dependency information between libstdc++ and libgcc_s to begin with. Regenerate configure scripts to reflect libtool.m4 change. 2022-10-09 Olivier Hainque <hainque@adacore.com> * libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker and friends for rtp !large. Assume the linker has the required abilities and set lt_cv_deplibs_check_method. gcc/ * config.gcc (*vxworks*): Add t-slibgcc fragment if enable_shared. libgcc/ * config.host (*vxworks*): When enable_shared, add libgcc and crtstuff "shared" fragments for rtp except large code model.

2022-04-05libbacktrace: don't skip initial aligned byte in uncompressed blockIan Lance Taylor1-1/+1
Patch from Rui Ueyama, who says: libbacktrace occasionally fails to decompress compressed debug info even though the sections contain valid zlib streams. The cause of the issue is an off-by-one error. If a zlib data block is a plain data (uncompressed data), the next two bytes contain the size of the block. These two bytes value is byte- aligned, so if we read-ahead more than 8 bits, we need to unread it. So, the correct condition to determine whether or not we need to unread a byte is bits >= 8 and not bits > 8. Due to this error, if the last read bits happened to end at a byte boundary, the next byte would be skipped. That caused the decompression failure. This bug was originally reported against the mold linker. rui314/mold#402 * elf.c (elf_zlib_inflate): Don't skip initial aligned byte in uncompressed block.
