From a0e28e54675fd92e73df71fed5d4f6c718f40102 Mon Sep 17 00:00:00 2001 From: Kevin Buettner Date: Thu, 9 Jul 2015 16:05:31 -0700 Subject: [PATCH] rx-tdep.c: Use target_read_code instead of target_read_memory. This change causes the prologue scanner and the frame type scanner in rx-tdep.c to use target_read_code() instead of target_read_memory(). This change allows these instruction scanners to operate much more quickly due to the fact that target_read_code() can potentially read from a cache maintained by GDB. gdb/ChangeLog: * rx-tdep.c (rx_get_opcode_byte): Use target_read_code instead of target_read_memory. --- gdb/ChangeLog | 5 +++++ gdb/rx-tdep.c | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 8ab1330e9bd..507042819cc 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2015-07-10 Kevin Buettner + + * rx-tdep.c (rx_get_opcode_byte): Use target_read_code instead + of target_read_memory. + 2015-07-10 Andrew Burgess * tui/tui-win.c (tui_set_win_height): Use a cleanup to free the diff --git a/gdb/rx-tdep.c b/gdb/rx-tdep.c index 8442c765f89..0bd91ff5f4b 100644 --- a/gdb/rx-tdep.c +++ b/gdb/rx-tdep.c @@ -204,7 +204,7 @@ rx_get_opcode_byte (void *handle) int status; gdb_byte byte; - status = target_read_memory (opcdata->pc, &byte, 1); + status = target_read_code (opcdata->pc, &byte, 1); if (status == 0) { opcdata->pc += 1; -- 2.30.2
