This patch resolves PR c++/84969 which is an ICE in the middle-end after emitting a "sorry, unimplemented" message, and is a regression from earlier releases of GCC. This issue is that after encountering a function call requiring an unreasonable amount of stack space, the code continues and falls foul of an assert checking that stack pointer has been correctly updated. The fix is to (locally) consider aborted function calls as "no return", which skips this downstream sanity check. 2022-03-10 Roger Sayle <ro...@nextmovesoftware.com> gcc/ChangeLog PR c++/84964 * calls.cc (expand_call): Ignore stack adjustments after sorry. gcc/testsuite/ChangeLog PR c++/84964 * g++.dg/other/pr84964.C: New test case.
