Subject: [release-branch.go1.26] simd/archsimd: correct algorithm name in SHA256 ops documentation
X-Git-Tag: go1.26.0~2
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=bf69803f97c1afadcfb29fea820326ffe8e87c6d;p=gostls13.git

[release-branch.go1.26] simd/archsimd: correct algorithm name in SHA256 ops documentation

The three SHA256 ops (SHA256Message1, SHA256Message2 and SHA256TwoRounds)
all incorrectly referred to the SHA1 algorithm in their documentation
rather than SHA256.
