MIPS test traces for MIPT-MIPS Simulator.
| Name | Description | |
|---|---|---|
| add.s | ✓ | simplest test for add instruction |
| bubble_sort.s | ✓ | bubble sort of 20 integers, contains a lot of branches |
| corner.s | ? | naughty/corner cases from our debug experience |
| factorial.s | ✘ | recursive implementation of factorial |
| fib.s | ✓ | loop implementation of Fibonacci numbers |
| dc_ic_stress.s | ✓ | a data and instruction memory stress based on random memory access pattern |
| dc_stress.s | ✓ | a data-only memory stress based on random memory access pattern |
| move.s | ✓ | just a single move pseudo-instruction |
| smc.s | ✘ | self-modifying MIPS code, modification is performed 'in-flight' |
| static_arrays.s | ✓ | example of a memory-located static array |
Torture tests were developed as a part of SPIM S20 MIPS Simulator. SPIM source files are distributed under Free BSD license (see file header). Copyright (c) 1990-2010, James R. Larus. All rights reserved.
We separated tests for MIPS32 and MIPS64 versions, as these architectures have different flow to initialize negative value or all-ones value.
| Name | Description | |
|---|---|---|
| tt.core.universal.s | ✓ | Instructions which behave similarly in MIPS32 and MIPS64 |
| tt.core32.s | ✓ | Tests MIPS32-specific instruction behavior |
| tt.core32.le.s | ✓ | Tests MIPS32-specific and little-endian instruction behavior |
| tt.core64.s | ✓ | MIPS64-specific version of tests |
| tt.core64.le.s | ✓ | Tests MIPS64-specific and little-endian instruction behavior |
GNU binutils for MIPS should be installed and have the following shortcuts:
mips-linux-gnu-as is an assembler for MIPS ISA
mips-linux-gnu-ld is a linker for MIPS object files
mips-linux-gnu-objdump dumps content of MIPS binary files (also disassembles instructions)
MIPT-MIPS wiki has an instruction how to get and build MIPS binutils: https://github.com/MIPT-ILab/mipt-mips/wiki/MIPS-binutils
Additionally, you may look inside get-binutils.sh script. The script is used to install GNU Binutils on CI hostings.
Use make command to build all the traces or make tracename.out to build one trace. You may specify local mips-linux-gnu-as and mips-linux-gnu-ld binaries with MIPS_AS= and MIPS_LD= Make variables.
In order to create MIPS binary file manually do the following steps:
- create a file with assember code using and text editor
- save it as
<test name>.s - generate an object file:
mips-linux-gnu-as <test name>.s -o <test name>.o - convert the object file into the binary file:
mips-linux-gnu-ld <test name>.o -o <test name>.out - (optionally) look the content of .out using (pay attention only to .text section):
mips-linux-gnu-objdump -D <test name>.out
