2022-04-05libbacktrace: don't skip initial aligned byte in uncompressed blockIan Lance Taylor
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.

2021-12-28Libbacktrace: Fix the use of newline in sed replacementFrancois-Xavier Coudert
On non-ELF targets, the Makefile needs a newline inside the sed REPLACE string. The way it is currently done fails with GNU Make < 4, but GCC only requires "GNU make version 3.80 (or later)". The portable solution is given in the autoconf manual: https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Newlines-in-Make-Rules.html libbacktrace/ChangeLog: PR libbacktrace/103822 * Makefile.am: Fix newline. * Makefile.in: Regenerate.

2020-12-05Darwin : Update libtool and dependencies for Darwin20 [PR97865]Iain Sandoe
The change in major version (and the increment from Darwin19 to 20) caused libtool tests to fail which resulted in incorrect build settings for shared libraries. We take this opportunity to sort out the shared undefined symbols state rather than propagating the current unsound behaviour into a new rev. This change means that we default to the case that missing symbols are considered an error, and if one wants to allow this intentionally, the confiuration for that case should be set appropriately. Three existing cases need undefined dynamic lookup: libitm, where there is already a configuration mechanism to add the flags. libcc1, where we add simple configuration to add the flags for Darwin. libsanitizer, where we can add to the existing extra flags. libcc1/ChangeLog: PR target/97865 * Makefile.am: Add dynamic_lookup to LD flags for Darwin. * configure.ac: Test for Darwin host and set a flag. * Makefile.in: Regenerate. * configure: Regenerate. libitm/ChangeLog: PR target/97865 * configure.tgt: Add dynamic_lookup to XLDFLAGS for Darwin. * configure: Regenerate. libsanitizer/ChangeLog: PR target/97865 * configure.tgt: Add dynamic_lookup to EXTRA_CXXFLAGS for Darwin. * configure: Regenerate.
