PR target/14798: gcc: * sh.c (pragma_interrupt, trap_exit, sp_switch): Remove variable. (pragma_trap, pragma_nosave_low_regs): Likewise. (current_function_anonymous_args): Likewise. (sh_deferred_function_attributes): New variable. (sh_deferred_function_attributes_tail): Likewise. (print_operand): For '@', look up trap_exit attribute. (calc_live_regs): Look up trapa_handler attribute. For trapa handlers, save/restore fpscr, but don't do any other interrupt-specific saves. Don't save r0..r7 if the nosave_low_regs attribute is in effect. Fix check for partially saved registers to check for SHmedia. (sh_expand_prologue, sh_expand_epilogue): Look up sp_switch attribute. (sh_output_function_epilogue): Don't clear any of the removed variables. (sh_insert_attributes): Don't check pragma_interrupt. Insert deferred attributes. Check that interrupt attribute is present for other attributes that require its presence. (sh_attribute_table): Add new attributes trapa_handler and nosave_low_regs. (sh_handle_sp_switch_attribute, sh_handle_trap_exit_attribute): Don't check for pragma_interrupt. Don't store argument. * sh.h (pragma_interrupt, sp_switch): Don't declare. (sh_deferred_function_attributes): Declare. (sh_deferred_function_attributes_tail): Likewise. * sh.md (sp_switch_1): Add operand. Change generator caller. (sh_pr_interrupt, sh_pr_trapa, sh_pr_nosave_low_regs): Remove. (*return_i): Don't use when trap_exit attribute is in effect. (*return_trapa): New insn pattern. * sh-c.c: New file. * config.gcc (sh[123456ble]*-* | sh-*-*): New trailer stanza, setting c_target_objs and cxx_target_objs. * t-sh: Add rule for sh-c.o. gcc/testsuite: * gcc.dg/pragma-isr.c: Added target sh[1234ble]*-*-*. * gcc.dg/pragma-isr2.c, gcc.dg/pragma-isr-trapa.c: New tests. * gcc.dg/pragma-isr-trapa2.c: Likewise. * gcc.dg/pragma-isr-nosave_low_regs.c: Likewise. * gcc.dg/pragma-isr-trap_exit.c: Likewise. * gcc.dg/attr-isr.c, gcc.dg/attr-isr-trapa.c: Likewise. * gcc.dg/attr-isr-trap_exit.c: Likewise. * gcc.dg/attr-isr-nosave_low_regs.c: Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
