From fc97c882f443060dffd8eb56a6b8784e52096c86 Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Mon, 17 Sep 2018 12:36:37 +0200 Subject: [PATCH] sha/asm/keccak1600-s390x.pl: resolve -march=z900 portability issue. Negative displacement in memory references was not originally specified, so that for maximum coverage one should abstain from it, just like with any other extension. [Unless it's guarded by run-time switch, but there is no switch in keccak1600-s390x.] Reviewed-by: Tim Hudson Reviewed-by: Richard Levitte (Merged from https://github.com/openssl/openssl/pull/7239) --- crypto/sha/asm/keccak1600-s390x.pl | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/crypto/sha/asm/keccak1600-s390x.pl b/crypto/sha/asm/keccak1600-s390x.pl index 3bce19be9e..1184cf233e 100755 --- a/crypto/sha/asm/keccak1600-s390x.pl +++ b/crypto/sha/asm/keccak1600-s390x.pl @@ -432,9 +432,9 @@ SHA3_absorb: lrvg %r0,0($inp) la $inp,8($inp) xg %r0,0(%r1) - la %r1,8(%r1) a${g}hi $len,-8 - stg %r0,-8(%r1) + stg %r0,0(%r1) + la %r1,8(%r1) brct $bsz,.Lblock_absorb stm${g} $inp,$len,$frame+3*$SIZE_T($sp) -- 2.25.1
