openbsd/src/lib/libcrypto/arch, branch libressl-v3.8.0 A mirror of https://github.com/libressl/openbsd.git https://git.lua4.win/openbsd/atom?h=libressl-v3.8.0 2023-04-15T18:23:54+00:00 Stop building GF2m assembly 2023-04-15T18:23:54+00:00 tb 2023-04-15T18:23:54+00:00 urn:sha1:aaaca473ab5066072557d54411e5d55740dd8e66 GF2m support will be removed shortly. In the interim drop some of this unused code already and let it fall back to the C implementation. ok jsing Sprinkle a few BTI instructions into the arm64 assembly files and pass 2023-04-05T11:07:40+00:00 kettenis 2023-04-05T11:07:40+00:00 urn:sha1:ecd00d4b9ba61bd64b589e0989e8b51d76a2327a -mmark-bti-property to indicate those now have BTI support. ok jsing@, deraadt@ Replace bn_sub_part_words() with bn_sub(). 2023-02-22T05:57:19+00:00 jsing 2023-02-22T05:57:19+00:00 urn:sha1:7236757e326b2c939f79a4239220a0cc2bf30ef5 Now that bn_sub() handles word arrays with potentially different lengths, we no longer need bn_sub_part_words() - call bn_sub() instead. This allows us to entirely remove the unnecessarily complex bn_sub_part_words() code. ok tb@ Enable s2n-bignum word_clz() on amd64. 2023-02-16T11:13:05+00:00 jsing 2023-02-16T11:13:05+00:00 urn:sha1:02f91f3325f965a313f0cffe5053a084d05a84ea The BN_num_bits_word() function is a hot path, being called more than 80 million times during a libcrypto regress run. The word_clz() implementation uses five instructions to do the same as the generic code that uses more than 60 instructions. Discussed with tb@ Remove the now empty bn_asm.c. 2023-01-31T06:17:11+00:00 jsing 2023-01-31T06:17:11+00:00 urn:sha1:0019a0499b5d8bc46dc5e1e2f3991c796603d31a This rather misnamed file (bn_asm.c) previously contained the C code that was needed to build libcrypto bignum on platforms that did not have assembly implementations of the functions it contained. Remove sparc related files from libcrypto. 2023-01-31T05:09:34+00:00 jsing 2023-01-31T05:09:34+00:00 urn:sha1:813266ead2a42465155e4af3e2daa71bcc88d54d The sparc platform got retired a while back, however some parts remained hiding in libcrypto. Mop these up (along with the bn_arch.h that I introduced). Spotted by and ok tb@ Use s2n-bignum assembly implementations for libcrypto bignum on amd64. 2023-01-29T14:00:41+00:00 jsing 2023-01-29T14:00:41+00:00 urn:sha1:4e1fab63a267fba43456f4cf3909f8d17ca6aee7 This switches the core bignum assembly implementations from x86_64-gcc.c to s2n-bignum for amd64. ok miod@ tb@ Provide an implementation of bn_sqr() that calls s2n-bignum's bignum_sqr(). 2023-01-21T17:29:56+00:00 jsing 2023-01-21T17:29:56+00:00 urn:sha1:f0336de474be059a63ecd6670f0c82b4aa9f9888 ok tb@ Replace BN_DIV3W with HAVE_BN_DIV_3_WORDS (in bn_arch.h). 2023-01-20T10:07:52+00:00 jsing 2023-01-20T10:07:52+00:00 urn:sha1:f0cba741581d1b230d658b4fcc93b802ac49a5f1 ok tb@ Remove non-visible and unused OPENSSL_wipe_cpu and OPENSSL_atomic_add 2023-01-17T15:04:27+00:00 miod 2023-01-17T15:04:27+00:00 urn:sha1:a7f48cec18a6702191b620e72d8ffa41cd9173bc interfaces, and remove empty assembly OPENSSL_cpuid_setup routines - the default empty C fallback will work as good. ok jsing@
