| 0001-Fixed-miscompilation-of-unw_getcontext-on-ARM.patch | Fixed miscompilation of unw_getcontext() on ARM | Ian Zborovsky <ian@veego.io> | no | 2024-05-06 | ||
| fix-arm64-build.diff | Made -nostdlib depend on exception support When libunwind is configured to provide the Itanium Level 1 Exception Support it needs to avoid linking in any compiler runtime libraries that already provide that support (for example, libgcc_s.so) in order to avoid duplicate symbols or ODR violations. This caused a problem on more recent GCC editions because of some dark magic in which libgcc_s.so is actually a linker script instead of a shared object so the library will be underlinked on some platforms. The use of `-nostdlib` should be limited to only the case in which the optional exception support is selected at configure time. When that is the case, we can assume the developer knows what they're doing (they're writing their own exception handling stack) and can pass the right LDADD explcitly as required. This changes makes the use of `-nostdlib` and `-lc -lgcc_s` dependent on the configure-time `--enable-cxx-exceptions=yes`, which is not the default. |

| 457612f470f8c0e718cdf7f14ef1ecb583f3b3a6.patch | Fix bad prototype for malloc() in test The unit test Gtest-nomalloc.c had an incorrect prototype for malloc() which caused newer compilers to fail compiling for newer C editions. Corrected the prototype and corrected a few other errors. The unit now compiles using GCC with `CFLAGS=-Wall -Wextra -pedantic -C11` with no warnings, which is the minimum requirement. Added the tests/unw_test.h header as a first step to cleaning up some unit tests further. |
