2023-08-08Fix handling of the "0:" label in arm-xlate.plTom Cosgrove
When $label == "0", $label is not truthy, so `if ($label)` thinks there isn't a label. Correct this by looking at the result of the s/// command. Verified that there are no changes in the .S files created during a normal build, and that the "0:" labels appear in the translation given in the error report (and they are the only difference in the before and after output).

2023-02-08Restrict the Arm 'LDR REG, =VALUE' pseudo instruction on Neon, to appease clangTom Cosgrove
Unlike gcc, the clang assembler has issues with the maximum value of the literal in the `ldr REG, #VALUE` pseudo-instruction (where the assembler places the value into a literal pool and generates a PC-relative load from that pool) when used with Neon registers. Specifically, while dN refers to 64-bit Neon registers, and qN refers to 128-bit Neon registers, clang assembly only supports a maximum of 32-bit loads to either with this instruction. Therefore restrict accordingly to avoid breakage when building with clang. clang appears to support the correct maximums with the scalar registers xN etc. This will prevent the kind of breakage we saw when #19914 was merged (which has since been fixed by #20202) - assembly authors will need to manually apply the literal load, as is done in #20202. None of the Arm assembler code uses this pseudo-instruction anyway, as it doesn't seem to avoid duplication of constants.

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).

"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...
