2020-12-09Read MIDR_EL1 system register on aarch64Fangming.Fang
MIDR_EL1 system register exposes microarchitecture information so that people can make micro-arch related optimization such as exposing as much instruction level parallelism as possible. MIDR_EL1 register can be read only if HWCAP_CPUID feature is supported.

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.

2018-06-03{arm64|x86_64}cpuid.pl: add special 16-byte case to OPENSSL_memcmp.Andy Polyakov
OPENSSL_memcmp is a must in GCM decrypt and general-purpose loop takes quite a portion of execution time for short inputs, more than GHASH for few-byte inputs according to profiler. Special 16-byte case takes it off top five list in profiler output. Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/6312)
