Hennadii Stepanov	dd3e0fa125	build: Fix false positive `CHECK_ATOMIC` test for clang-15	7 months ago
Hennadii Stepanov	f8ca1357c8	build: Fix check whether `-latomic` needed	10 months ago
fanquake	ebc7063c80	doc: update docs for CHECK_ATOMIC macro ... Clarify that supported versions of GCC are not affected, and that Clang prior to version 15 still requires the explicit -latomic linking, when compiling for 32-bit.	1 year ago
Andrew Chow	4de4221ab4	build: Check for std::atomic::exchange rather than std::atomic_exchange ... Our usage of std::atomic is with it's own exchange function, not std::atomic_exchange. So we should be looking specifically for that function. Additionally, -pthread and -lpthread have an effect on whether -latomic will be needed, so the atomics check needs to use these flags as well. This will make the flags in use better match what is actually used when linking. This removes the need for -latomic for riscv builds, which resolves a guix cross architecture reproducibility issue.	2 years ago
MarcoFalke	fa25ce45e9	build: improve macro for testing -latomic requirement	4 years ago
fanquake	54ce4fac80	build: improve macro for testing -latomic requirement ... riscv builds are currently failing because -latomic isn't being linked against, when it is needed: ```bash /home/ubuntu/build/bitcoin/distsrc-riscv64-linux-gnu/src/bitcoin-util.cpp:98: undefined reference to `__atomic_exchange_1' ``` This exteneds our macro to ensure that -latomic is linked against when required.	4 years ago
