2020-02-17Also check for errors in x86_64-xlate.pl.David Benjamin
In https://github.com/openssl/openssl/pull/10883, I'd meant to exclude the perlasm drivers since they aren't opening pipes and do not particularly need it, but I only noticed x86_64-xlate.pl, so arm-xlate.pl and ppc-xlate.pl got the change. That seems to have been fine, so be consistent and also apply the change to x86_64-xlate.pl. Checking for errors is generally a good idea.

2020-01-22Do not silently truncate files on perlasm errorsDavid Benjamin
If one of the perlasm xlate drivers crashes, OpenSSL's build will currently swallow the error and silently truncate the output to however far the driver got. This will hopefully fail to build, but better to check such things. Handle this by checking for errors when closing STDOUT (which is a pipe to the xlate driver).

2019-09-16Unify all assembler file generatorsRichard Levitte
They now generally conform to the following argument sequence: script.pl "$(PERLASM_SCHEME)" [ C preprocessor arguments ... ] \ $(PROCESSOR) <output file> However, in the spirit of being able to use these scripts manually, they also allow for no argument, or for only the flavour, or for only the output file. This is done by only using the last argument as output file if it's a file (it has an extension), and only using the first argument as flavour if it isn't a file (it doesn't have an extension). While we're at it, we make all $xlate calls the same, i.e. the $output argument is always quoted, and we always die on error when trying to start $xlate. There's a perl lesson in this, regarding operator priority... This will always succeed, even when it fails: open FOO, "something" || die "ERR: $!"; The reason is that '||' has higher priority than list operators (a function is essentially a list operator and gobbles up everything following it that isn't lower priority), and since a non-empty string is always true, so that ends up being exactly the same as: open FOO, "something"; This, however, will fail if "something" can't be opened: open FOO, "something" or die "ERR: $!"; The reason is that 'or' has lower priority that list operators, i.e. it's performed after the 'open' call.

2019-02-16ARM assembly pack: make it Windows-friendly.Andy Polyakov
"Windows friendliness" means a) flipping .thumb and .text directives, b) always generate Thumb-2 code when asked(*); c) Windows-specific references to external OPENSSL_armcap_P. (*) so far *some* modules were compiled as .code 32 even if Thumb-2 was targeted. It works at hardware level because processor can alternate between the modes with no overhead. But clang --target=arm-windows's builtin assembler just refuses to compile .code 32...

2017-11-28Fix chacha-armv4.pl with clang -fno-integrated-as.David Benjamin
The __clang__-guarded #defines cause gas to complain if clang is passed -fno-integrated-as. Emitting .syntax unified when those are used fixes this. This matches the change made to ghash-armv4.pl in 6cf412c473d8145562b76219ce3da73b201b3255.

2016-10-10Remove trailing whitespace from some files.David Benjamin
The prevailing style seems to not have trailing whitespace, but a few lines do. This is mostly in the perlasm files, but a few C files got them after the reformat. This is the result of: find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//' Then bn_prime.h was excluded since this is a generated file. Note mkerr.pl has some changes in a heredoc for some help output, but other lines there lack trailing whitespace too.

2016-03-11Fix some assembler generating scripts for better unificationRichard Levitte
Some of these scripts would recognise an output parameter if it looks like a file path. That works both in both the classic and new build schemes. Some fo these scripts would only recognise it if it's a basename (i.e. no directory component). Those need to be corrected, as the output parameter in the new build scheme is more likely to contain a directory component than not. Reviewed-by: Andy Polyakov <appro@openssl.org>
