### Config settings ############################################################
|
||||
|
||||
# Bazel does not support nested selects, so we need config settings with the
|
||||
# various combinations of OS and CPU.
|
||||
|
||||
# Switch to drop the GCC `_Unwind_*` ABI compatibility layer (src/unwind/*.c)
|
||||
# from the build. These sources implement `_Unwind_GetLanguageSpecificData`,
|
||||
# `_Unwind_ForcedUnwind`, `_Unwind_Resume`, etc. - the very symbols that
|
||||
# libgcc_s also provides. When Bazel builds libunwind as a dylib (its default
|
||||
# behavior in fastbuild), these symbols get exported and at runtime the dynamic
|
||||
# loader resolves the libstdc++ / pthread_exit unwinding paths to libunwind's
|
||||
# DWARF-based implementations instead of libgcc_s's, causing crashes such as:
|
||||
# _Unwind_ForcedUnwind -> __gxx_personality_v0 ->
|
||||
# __libunwind_Unwind_GetLanguageSpecificData -> SEGV in
|
||||
# _ULx86_64_dwarf_find_proc_info.
|
||||
#
|
||||
# brpc only consumes libunwind's native `unw_*` API (provided by src/mi/), so
|
||||
# omitting src/unwind/*.c is safe and is the same effect autoconf gets via
|
||||
# `--version-script` in the upstream Makefile (the make-built libunwind.so does
|
||||
# not export `_Unwind_*` either - see CI's init-ut-make-config action).
|
||||
#
|
||||
# Enable with: --define=libunwind_hide_unwind_symbols=true

### Config settings ############################################################
|
||||
|
||||
# Bazel does not support nested selects, so we need config settings with the
|
||||
# various combinations of OS and CPU.
|
||||
|
||||
# Switch to drop the GCC `_Unwind_*` ABI compatibility layer (src/unwind/*.c)
|
||||
# from the build. These sources implement `_Unwind_GetLanguageSpecificData`,
|
||||
# `_Unwind_ForcedUnwind`, `_Unwind_Resume`, etc. - the very symbols that
|
||||
# libgcc_s also provides. When Bazel builds libunwind as a dylib (its default
|
||||
# behavior in fastbuild), these symbols get exported and at runtime the dynamic
|
||||
# loader resolves the libstdc++ / pthread_exit unwinding paths to libunwind's
|
||||
# DWARF-based implementations instead of libgcc_s's, causing crashes such as:
|
||||
# _Unwind_ForcedUnwind -> __gxx_personality_v0 ->
|
||||
# __libunwind_Unwind_GetLanguageSpecificData -> SEGV in
|
||||
# _ULx86_64_dwarf_find_proc_info.
|
||||
#
|
||||
# brpc only consumes libunwind's native `unw_*` API (provided by src/mi/), so
|
||||
# omitting src/unwind/*.c is safe and is the same effect autoconf gets via
|
||||
# `--version-script` in the upstream Makefile (the make-built libunwind.so does
|
||||
# not export `_Unwind_*` either - see CI's init-ut-make-config action).
