From 4ec77dde62f8c14df9403abf7b10a2455ea72125 Mon Sep 17 00:00:00 2001 From: Tim Newsome Date: Tue, 27 Dec 2016 11:34:50 -0800 Subject: Use compressed code if the target supports it. The main change was to read misa before running any other test. If misa indicates C is supported, then use compressed code. This required changing some tests, mostly to ensure correct alignment. The single step test also needs to know the correct addresses to step through in compressed code. Only print at most 1000 lines from each log file. --- debug/programs/step.S | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'debug/programs/step.S') diff --git a/debug/programs/step.S b/debug/programs/step.S index 6601548..3e7b42e 100644 --- a/debug/programs/step.S +++ b/debug/programs/step.S @@ -11,14 +11,18 @@ main: nop // 0x14 one: beq zero, t0, one // 0x18 - jal two // 0x1c + // Use t0 instead of ra to force a 32-bit opcode in C mode.
