From: Torbjörn SVENSSON <[email protected]>
For armv8.1-m.main targets, `long long` needs to be placed in an even
numbered register pair.
Using r3 gives errors like for the long long operand:
asm-hard-reg-6.c:61:3: error: register r3 for operand 1 isn't suitable for data
type
gcc/testsuite/ChangeLog:
PR testsuite/124328
* gcc.dg/asm-hard-reg-6.c: Swap value in r2 and r3.

I've tested this change on top of r17-2833-g32657f29f91871 and
r16-9480-g967a69a03886ebd6.
Ok for trunk and releases/gcc-16?
