PR middle-end/65958 * config/arm/linux-elf.h (STACK_CHECK_STATIC_BUILTIN): Define. * config/arm/arm-protos.h (output_probe_stack_range): Declare. * config/arm/arm.c: Include common/common-target.h. (use_return_insn): Return 0 if the static chain register was saved above a non-APCS frame. (arm_compute_static_chain_stack_bytes): Adjust for stack checking. (struct scratch_reg): New. (get_scratch_register_on_entry): New function. (release_scratch_register_on_entry): Likewise. (arm_emit_probe_stack_range): Likewise. (output_probe_stack_range): Likewise. (arm_expand_prologue): Factor out code dealing with the IP register for nested function and adjust it for stack checking. Invoke arm_emit_probe_stack_range if static builtin stack checking is enabled. (thumb1_expand_prologue): Sorry out if static builtin stack checking is enabled. (arm_expand_epilogue): Add the saved static chain register, if any, to the amount of pre-pushed registers to pop. (arm_frame_pointer_required): Return true if static stack checking is enabled and we want to catch the exception with the EABI unwinder. * config/arm/unspecs.md (UNSPEC_PROBE_STACK): New constant. (UNSPEC_PROBE_STACK_RANGE): Likewise. * config/arm/arm.md (probe_stack): New insn. (probe_stack_range): Likewise. From-SVN: r227860 |

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. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
