From a99bf2ea9449d0e8120682feb2bedc398adab8b2 Mon Sep 17 00:00:00 2001 From: Tarek BOCHKATI Date: Tue, 25 Feb 2020 19:35:44 +0100 Subject: semihosting: reorganize semihosting commands the same semihosting handlers chain is declared twice: 1. in src/target/armv4_5.c 2. in src/target/riscv/riscv.c to make it simpler we moved the declaration into 'src/target/semihosting_common.c' under semihosting_common_handlers[]. then we used this into both of armv4_5.c and riscv.c Change-Id: If813b3fd5eb2476658f1308f741c4e805141f617 Signed-off-by: Tarek BOCHKATI Reviewed-on: http://openocd.zylin.com/5473 Tested-by: jenkins Reviewed-by: Muhammad Omair Javaid Reviewed-by: Tim Newsome Reviewed-by: Liviu Ionescu --- src/target/armv4_5.c | 32 ++------------------------------ src/target/riscv/riscv.c | 39 ++------------------------------------- src/target/semihosting_common.c | 41 ++++++++++++++++++++++++++++++++++++----- 3 files changed, 40 insertions(+), 72 deletions(-) diff --git a/src/target/armv4_5.c b/src/target/armv4_5.c index 7a72a0bf..6c487626 100644 --- a/src/target/armv4_5.c +++ b/src/target/armv4_5.c @@ -1098,10 +1098,7 @@ static int jim_mcrmrc(Jim_Interp *interp, int argc, Jim_Obj * const *argv) return JIM_OK;
