Ok,
So the problem is that I had this patch:
--- openssl-1.0.1.orig/crypto/perlasm/x86_64-xlate.pl
+++ openssl-1.0.1/crypto/perlasm/x86_64-xlate.pl
@@ -786,7 +786,7 @@
chomp($line);
- $line =~ s|[#!].*$||; # get rid of asm-style comments...
+# $line =~ s|[#!].*$||; # get rid of asm-style comments...
$line =~ s|/\*.*\*/||; # ... and C-style comments...
$line =~ s|^\s+||; # ... and skip white spaces in beginning
If I remember right, this was needed to be able to use preprocessor
commands in the .S files. (The file was also renamed from .s to
.S)
But I don't need that anymore, so I removed that patch, and you
can close this.
