PR rtl-optimization/50063 * config/avr/avr.md (movhi_sp_r): Handle -1 (unknown IRQ state) and 2 (8-bit SP) in operand 2. * config/avr/avr.c (avr_prologue_setup_frame): Adjust prologue setup to use movhi_sp_r instead of vanilla move to write SP. Adjust REG_CFA notes to superseed unspec. (expand_epilogue): Adjust epilogue setup to use movhi_sp_r instead of vanilla move. As function body might contain CLI or SEI: Use irq_state 0 (IRQ known to be off) only with TARGET_NO_INTERRUPTS. Never use irq_state 1 (IRQ known to be on) here. From-SVN: r184461 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
