+Subject: Fix constant division for AMD64 assembly on Solaris/x86
+X-Git-Url: http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commitdiff_plain;h=43376891c01f4aff1fbfb23beafebb5adfd0868c
+
+Fix constant division for AMD64 assembly on Solaris/x86
+
+* configure.ac (gcry_cv_gcc_as_const_division_ok): Add new check for
+constant division in assembly and test for "-Wa,--divide" workaround.
+(gcry_cv_gcc_amd64_platform_as_ok): Check for also constant division.
+--
+
+Appearantly on Solaris/x86 '/' character is treated as begining of line
+comment by GNU as. This causes problems when compiling SHA-1 SSSE3

+Patch adds detection of this feature and attempts to workaround issue with by
+adding "-Wa,--divide" to CPPFLAGS. If workaround does not work (old GAS on
+Solaris/x86), we'll disable AMD64 assembly.
+
+[v3]:
+ - Update CPPFLAGS after testing instead of CFLAGS.
