PR middle-end/45234 * rtl.h (enum global_rtl_index): Add GR_VIRTUAL_PREFERRED_STACK_BOUNDARY. (LAST_VIRTUAL_POINTER_REGISTER): Define. (virtual_preferred_stack_boundary_rtx, VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM): Define. (LAST_VIRTUAL_REGISTER): Increase by one. (REGNO_PTR_FRAME_P): Use LAST_VIRTUAL_POINTER_REGISTER instead of LAST_VIRTUAL_REGISTER. * function.c (instantiate_new_reg): Handle virtual_preferred_stack_boundary_rtx. * emit-rtl.c (init_virtual_regs): Handle VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM. (init_emit_regs): Initialize virtual_preferred_stack_boundary_rtx. * explow.c (round_push): If crtl->preferred_stack_boundary is smaller than MAX_SUPPORTED_STACK_ALIGNMENT, use virtual_preferred_stack_boundary_rtx alignment instead of crtl->preferred_stack_boundary alignment. (allocate_dynamic_stack_space): Use CONST_INT_P and REG_P macros. Never decrease crtl->preferred_stack_boundary, use crtl->preferred_stack_boundary or MAX_SUPPORTED_STACK_ALIGNMENT instead of PREFERRED_STACK_BOUNDARY. Don't modify stack_pointer_delta in dynamic allocation, even when size is constant. (probe_stack_range, anti_adjust_stack_and_probe): Use CONST_INT_P macro. * print-rtl.c (print_rtx): Handle VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM. * config/alpha/alpha.h (NONSTRICT_REG_OK_FP_BASE_P): Use LAST_VIRTUAL_POINTER_REGISTER instead of LAST_VIRTUAL_REGISTER. * config/frv/frv.c (frv_emit_movsi): Likewise. * config/arm/arm.c (thumb1_legitimate_address_p): Likewise. * config/rs6000/rs6000.c (virtual_stack_registers_memory_p): Likewise. * gcc.dg/torture/stackalign/alloca-6.c: New test. * gcc.target/i386/pr45234.c: New test. Revert: 2010-09-17 H.J. Lu <hongjiu.lu@intel.com> PR middle-end/45234 * calls.c (expand_call): Make sure that all variable sized adjustments are multiple of preferred stack boundary after stack alignment.

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.
