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.

2018-05-02bn/asm/*-mont.pl: harmonize with BN_from_montgomery_word.Andy Polyakov
Montgomery multiplication post-conditions in some of code paths were formally non-constant time. Cache access pattern was result-neutral, but a little bit asymmetric, which might have produced a signal [if processor reordered load and stores at run-time].

2016-03-08SPARCv9 assembly pack: unify build rules and argument handling.Andy Polyakov
Make all scripts produce .S, make interpretation of $(CFLAGS) pre-processor's responsibility, start accepting $(PERLASM_SCHEME). [$(PERLASM_SCHEME) is redundant in this case, because there are no deviataions between Solaris and Linux assemblers. This is purely to unify .pl->.S handling across all targets.] Reviewed-by: Richard Levitte <levitte@openssl.org>

This gets rid of the BEGINRAW..ENDRAW sections in crypto/bn/build.info. This also moves the assembler generating perl scripts to take the output file name as last command line argument, where necessary. Reviewed-by: Rich Salz <rsalz@openssl.org>
