From: sergiodj+buildbot@sergiodj.net To: gdb-testers@sourceware.org Subject: [binutils-gdb] class readable_regcache and pass readable_regcache to gdbarch pseudo_register_read and pseudo_register_read_value Date: Wed, 21 Feb 2018 11:47:00 -0000 [thread overview] Message-ID: <849d0ba802323fe05e3039ed5b22957db2c85a67@gdb-build> (raw) *** TEST RESULTS FOR COMMIT 849d0ba802323fe05e3039ed5b22957db2c85a67 *** Author: Yao Qi <yao.qi@linaro.org> Branch: master Commit: 849d0ba802323fe05e3039ed5b22957db2c85a67 class readable_regcache and pass readable_regcache to gdbarch pseudo_register_read and pseudo_register_read_value pseudo registers are either from raw registers or memory, so gdbarch methods pseudo_register_read and pseudo_register_read_value should have regcache object which only have read methods. In other words, we should disallow writing to regcache in these two gdbarch methods. In order to apply this restriction, this patch adds a new class readable_regcache, derived from reg_buffer, and it only has raw_read and cooked_read methods. regcache is derived from readable_regcache. This patch also passes readable_regcache instead of regcache to gdbarch methods pseudo_register_read and pseudo_register_read_value. This patch moves raw_read* and cooked_read* methods to readable_regcache, which is straightforward. One thing not straightforward is that I split regcache::xfer_part to readable_regcache::read_part and regcache::write_part, because readable_regcache can only have methods to read. readable_regcache is an abstract base class, and it has a pure virtual function raw_update, because I don't want readable_regcache know where these raw registers are from. They can be from either the target (readwrite regcache) or the regcache itself (readonly regcache). gdb: 2018-02-21 Yao Qi <yao.qi@linaro.org> * aarch64-tdep.c (aarch64_pseudo_register_read_value): Change parameter type to 'readable_regcache *'. * amd64-tdep.c (amd64_pseudo_register_read_value): Likewise. * arm-tdep.c (arm_neon_quad_read): Likewise.
