* libelftc: Fix a typo - FreeBSD's riscv port is little-endian.Joseph Koshy2024-12-311-1/+1
| | | | | | | | | | | This change brings the descriptor for target "elf64-riscv-freebsd" in line with its documentation. I missed this somehow when reviewing https://reviews.freebsd.org/D20768.

* Fix memory corruption in C++ demanglerJustine Tunney2024-05-101-1/+1
| | | | | | | | | | | | The __cxa_demangle_gnu3() and cpp_demangle_gnu3() functions segfault on various libcxxabi test cases due to a copy and paste error. This change fixes that. This is a subset of https://github.com/libcxxrt/libcxxrt/pull/34 which fixes the immediate problem. Reviewed by: imp, emaste (I think) Pull Request: https://github.com/freebsd/freebsd-src/pull/1222

| | | | | | | | | | | | | | | | | | | | | | Incorporate fixes from Dimitry Andric: - Use a BUFFER_GROW() macro to avoid rounding errors in capacity calculations. - Fix a bug introduced in [r3531]. - Fix handling of nested template parameters. Ticket: #581 This should fix a number of assertions on elftoolchain's cxxfilt, and allow it to correctly demangle several names that it could not handle before.
