Alex Rønne Petersen	2e3fac3626	test: rename backend=stage2 to backend=selfhosted, and add backend=auto ... backend=auto (now the default if backend is omitted) means to let the compiler pick whatever backend it wants as the default. This is important for platforms where we don't yet have a self-hosted backend, such as loongarch64. Also purge a bunch of redundant target=native.	2025-09-16 23:39:26 +02:00
Jacob Young	69abc945e4	aarch64: implement some safety checks ... Closes #24553	2025-07-26 17:31:04 -04:00
Jacob Young	8159ff8b81	x86_64: implement error set and enum safety ... This is all of the expected 0.14.0 progress on #21530, which can now be postponed once this commit is merged. This required rewriting the (un)wrap operations since the original implementations were extremely buggy. Also adds an easy way to retrigger Sema OPV bugs so that I don't have to keep updating #22419 all the time.	2025-02-15 03:45:21 -05:00
mlugg	b01d6b156c	compiler: add intcast_safe AIR instruction ... This instruction is like `intcast`, but includes two safety checks: * Checks that the int is in range of the destination type * If the destination type is an exhaustive enum, checks that the int is a named enum value This instruction is locked behind the `safety_checked_instructions` backend feature; if unsupported, Sema will emit a fallback, as with other safety-checked instructions. This instruction is used to add a missing safety check for `@enumFromInt` truncating bits. This check also has a fallback for backends which do not yet support `safety_checked_instructions`.
