Subject: [PATCH 1/4] arc: Add XML target features for Linux targets
Date: Thu, 26 Mar 2020 13:52:03 +0100 [thread overview]
Message-ID: <20200326125206.13120-2-shahab.vahedi@gmail.com> (raw)
In-Reply-To: <20200326125206.13120-1-shahab.vahedi@gmail.com>
From: Anton Kolesov <Anton.Kolesov@synopsys.com>
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:
2020-03-26 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_read_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.
