From 84f9fbe90e5429adb9dee68f04f44c92fa9e2345 Mon Sep 17 00:00:00 2001 From: Jiangshuai Li Date: Wed, 9 Nov 2022 19:50:35 +0800 Subject: [PATCH] gdb/csky just return type from csky_vector_type() for vector resgisters Some gdb stubs may not describe the type for vector registers in the tdesc-xml and only send bitsize="128", gdb can't deal with a reg with default type int with bitsize==128. So Just return csky_vector_type() for vector resgisters. --- gdb/csky-tdep.c | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) diff --git a/gdb/csky-tdep.c b/gdb/csky-tdep.c index ced1b032a7b..f293d204da2 100644 --- a/gdb/csky-tdep.c +++ b/gdb/csky-tdep.c @@ -711,6 +711,13 @@ csky_register_type (struct gdbarch *gdbarch, int reg_nr) return builtin_type (gdbarch)->builtin_int32; } + /* Vector register has 128 bits, and only in ck810.
