2024-07-17Merge bitcoin/bitcoin#28893: Fix SSE4.1-related issuesmerge-script
d440f13db02c82c842000abe4fe4d0c721a4ad3b crypto: Guard code with `ENABLE_SSE41` macro (Hennadii Stepanov) 6ec1ca7c85a4009b77e149a798a331592b96ea42 build: Fix test for SSE4.1 intrinsics (Hennadii Stepanov) Pull request description: 1. Fix the test for SSE4.1 intrinsics during build system configuration, which currently can be false positive, for example, when `CXXFLAGS="-mno-sse4.1"` provided. This PR fixes the test by adding the `_mm_blend_epi16` SSE4.1 function used in our codebase. 2. Guard `sha_x86_shani.cpp` code with `ENABLE_SSE41` macro as it uses the `_mm_blend_epi16` function from the SSE4.1 instruction set. It is possible that SHA-NI is enabled even when SSE4.1 is disabled, which causes compile errors in the master branch. Closes https://github.com/bitcoin/bitcoin/issues/28864.

2024-03-05crypto: Guard code with `ENABLE_SSE41` macroHennadii Stepanov
The code in `sha_x86_shani.cpp` uses the `_mm_blend_epi16` function from the SSE4.1 instruction set. However, it is possible that SHA-NI is enabled even when SSE4.1 is disabled. This changes avoid compilation errors in such a condition.
2024-02-29build: remove confusing and inconsistent disable-asm optionCory Fields
1. It didn't actually disable asm usage in our code. Regardless of the setting, asm is used in random.cpp and support/cleanse.cpp. 2. The value wasn't forwarded to libsecp as a user might have reasonably expected. 3. We now have the DISABLE_OPTIMIZED_SHA256 define which is what disable-asm actually did in practice. If there is any desire, we can hook DISABLE_OPTIMIZED_SHA256 up to a new configure option that actually does what it says.

2024-01-05crypto: remove use of BUILD_BITCOIN_INTERNAL macro in sha256Cory Fields
Replace it with a more explicit DISABLE_OPTIMIZED_SHA256 and clean up some. The macro was originally used by libbitcoinconsensus which opts out of optimized sha256 for the sake of simplicity. Also remove the BUILD_BITCOIN_INTERNAL define from libbitcoinkernel for now as it does not export an api. When it does we can pick a less confusing define to control its exports. Removing the define should have the effect of enabling sha256 optimizations for the kernel.
