From d9b6e047f60ce2129eff28ad1c6690949293366b Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 23 May 2022 10:59:13 -0700 Subject: [PATCH] Fix loongarch_iterate_over_regset_sections for non-native targets. Define a constant for the number of registers stored in a register set and use this with register_size to compute the size of the general-purpose register set in core dumps. This also fixes the build on hosts such as FreeBSD that do not define an elf_gregset_t type. --- gdb/loongarch-linux-tdep.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/gdb/loongarch-linux-tdep.c b/gdb/loongarch-linux-tdep.c index f13756dd003..bbb43abe13f 100644 --- a/gdb/loongarch-linux-tdep.c +++ b/gdb/loongarch-linux-tdep.c @@ -29,6 +29,11 @@ #include "trad-frame.h" #include "tramp-frame.h" +/* The general-purpose regset consists of 32 R registers, plus PC, + and BADV registers. */ + +#define LOONGARCH_LINUX_NUM_GREGSET (34) + /* Unpack an elf_gregset_t into GDB's register cache. */ static void @@ -172,8 +177,13 @@ loongarch_iterate_over_regset_sections (struct gdbarch *gdbarch, void *cb_data, const struct regcache *regcache) { - cb (".reg", sizeof (elf_gregset_t), sizeof (elf_gregset_t), - &loongarch_gregset, NULL, cb_data); + loongarch_gdbarch_tdep *tdep + = (loongarch_gdbarch_tdep *) gdbarch_tdep (gdbarch); + auto regs = tdep->regs; + int regsize = register_size (gdbarch, regs.r); + + cb (".reg", LOONGARCH_LINUX_NUM_GREGSET * regsize, + LOONGARCH_LINUX_NUM_GREGSET * regsize, &loongarch_gregset, NULL, cb_data); } /* Initialize LoongArch Linux ABI info. */ -- 2.30.2
