17404f8e6e Sema: emit compile error for comptime or inline call of function pointer 2023-01-31 17:15:34 +02:00
Isaac Freund
23b7d28896 std: restrict mem.span() and mem.len() to sentinel terminated pointers 
These functions are currently footgunny when working with pointers to
arrays and slices. They just return the stated length of the array/slice
without iterating and looking for the first sentinel, even if the
array/slice is a sentinel terminated type.

From looking at the quite small list of places in the standard
library/compiler that this change breaks existing code, the new code
looks to be more readable in all cases.

The usage of std.mem.span/len was totally unneeded in most of the cases
affected by this breaking change.

We could remove these functions entirely in favor of other existing
functions in std.mem such as std.mem.sliceTo(), but that would be a
somewhat nasty breaking change as std.mem.span() is very widely used for
converting sentinel terminated pointers to slices. It is however not at
all widely used for anything else.

Therefore I think it is better to break these few non-standard and
potentially incorrect usages of these functions now and at some later
time, if deemed worthwhile, finally remove these functions.

If we wait for at least a full release cycle so that everyone adapts to
this change first, updating for the removal could be a simple find and
replace without needing to worry about the semantics.

eb0c959b43 link-tests: update uuid test with new uuid values 
Changes only pertain arm64 as for x86_64 turns out we are
missing one additional feature which is synthesising unwind info
from only eh frame records, or at least this is what it looks like
when I analysed the output of Apple's ld.
