|

|

Stack pointer adjustment code in prologue missed a case of no
|
||||
callee-saved registers and a stack frame size bigger than 128 bytes.
|
||||
Handle that case.
|
||||
|
||||
This fixes the following gcc tests with call0 ABI:

* config/xtensa/xtensa.c (xtensa_expand_prologue): Add stack

pointer adjustment for the case of no callee-saved registers and

Xtensa hwloop_optimize segfaults when zero overhead loop is about to be

inserted as the first instruction of the function.

Insert zero overhead loop instruction into new basic block before the

loop when basic block that precedes the loop is empty.
