PR tree-optimization/94574 - aarch64: ICE during GIMPLE pass:ccp
In this PR the testcase ICEs because a BIT_INSERT_EXPR whose replaced bits are
not fully inside the container is generated. A size check is added to avoid
this kind of ICE.
gcc/ChangeLog:
PR tree-optimization/94574
* tree-ssa.c (non_rewritable_lvalue_p): Add size check when analyzing
whether a vector-insert is rewritable using a BIT_INSERT_EXPR.
gcc/testsuite/ChangeLog:
PR tree-optimization/94574
* gcc.dg/pr94574.c: New test.
