Tim Northover	19d2e42be2	ARM: don't return by popping PC if we have to adjust the stack afterwards. ... In mandatory tail calling conventions we might have to deallocate stack space used by our arguments before return. This happens after popping CSRs, so the pop cannot be turned into the return itself in this case. The else branch here was already a nop, so removing it as a tidy-up.	2021-07-21 09:35:14 +01:00
Tim Northover	d88f96dff3	ARM: support mandatory tail calls for tailcc & swifttailcc ... This adds support for callee-pop conventions to the ARM backend so that it can ensure a call marked "tail" is actually a tail call.	2021-05-28 11:10:51 +01:00
