From 4a6eddab8ec709180e6294ce3794768a511baf82 Mon Sep 17 00:00:00 2001 From: Richard Xia Date: Mon, 30 Oct 2017 15:44:21 -0700 Subject: [PATCH] Remove cache miss test from last AMO test. (#88) Follow-up to b68b39031a730ecc155ed87fba2ed5f111d0ab07. The 64KiB allocated by the code to force a cache miss makes it impossible to run the test from any memories that are smaller 64KiB, such as scratchpad memories or LIMs. Since this is trying to test microarchitectural behavior, they don't belong in these ISA tests anyway. --- isa/rv64ua/amoxor_d.S | 17 ----------------- 1 file changed, 17 deletions(-) diff --git a/isa/rv64ua/amoxor_d.S b/isa/rv64ua/amoxor_d.S index f446121..8305434 100644 --- a/isa/rv64ua/amoxor_d.S +++ b/isa/rv64ua/amoxor_d.S @@ -18,13 +18,6 @@ RVTEST_CODE_BEGIN li a1, 0xfffffffffffff800; \ la a3, amo_operand; \ sd a0, 0(a3); \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ - nop; nop; nop; nop; \ amoxor.d a4, a1, 0(a3); \ ) @@ -33,15 +26,6 @@ RVTEST_CODE_BEGIN # try again after a cache miss TEST_CASE(4, a4, 0x000000007ffff800, \ li a1, 1; \ - li a4, 16384; \ - add a5, a3, a4; \ - ld x0, 0(a5); \ - add a5, a5, a4; \ - ld x0, 0(a5); \ - add a5, a5, a4; \ - ld x0, 0(a5); \ - add a5, a5, a4; \ - ld x0, 0(a5); \ amoxor.d a4, a1, 0(a3); \ ) @@ -62,4 +46,3 @@ RVTEST_DATA_END .align 3 amo_operand: .dword 0 - .skip 65536 -- 2.30.2
