- Subject: [PATCH v2 2/4] arc: Add XML target features for Linux targets
- Authentication-results: sourceware.org; auth=none
- References: <20171026114020.10213-1-Anton.Kolesov@synopsys.com>
- References: <20171012012859.GJ8425@1170ee0b50d5>
Add XML target features for Linux targets. Compared to default
Linux features:
- Explicitly specify CPU machine.
- Remove baremetal only ILINK{,1,2} registers.
- Add LP_START and LP_END registers for hardware loops - required to properly
evaluate possible next instruction during software single instruction
stepping.
- Add BTA register which contains branch target address - address of next
instruction when processor is in the delay slot.
- ARC HS description also adds R30, R58 and R59 registers, specific to this
architecture.
gdb/ChangeLog:
yyyy-mm-dd Anton Kolesov <Anton.Kolesov@synopsys.com>
* arch/arc.h (arc_create_target_description): Support Linux targets.
* arch/arc.c (arc_create_target_description): Likewise.
* arc-tdep.c (arc_tdesc_init): Update invocation of
arc_create_target_description.
* features/Makefile (FEATURE_XMLFILES): Add new files.
* features/arc/aux-arcompact-linux.xml: New file.
* features/arc/aux-v2-linux.xml: Likewise.
* features/arc/core-arcompact-linux.xml: Likewise.
* features/arc/core-v2-linux.xml: Likewise.
* features/arc/aux-arcompact-linux.c: Generate.
* features/arc/aux-v2-linux.c: Likewise.
* features/arc/core-arcompact-linux.c: Likewise.
* features/arc/core-v2-linux.c: Likewise.
