Testsuite for the i860 version of the GNU assembler
|
3 |
|
|
---------------------------------------------------
|

|
|
|

|
|
This is a simple testsuite for the i860 assembler. It currently
|
6 |
|
|
consists mostly of testcases for checking that every instruction is
|
7 |
|
|
parsed correctly and that correct object code is generated (these
|
8 |
|
|
are called "blah.s"). The files called "blah-err.s" test for error
|
9 |
|
|
conditions.
|
10 |
|
|
|
11 |
|
|
The suite includes testcases for the base i860XR instruction set as well
|
12 |
|
|
as the enhanced i860XP instructions and control registers.
|
13 |
|
|
|
14 |
|
|
The expected results files were generated using the UNIX System V/i860
|
15 |
|
|
Release 4 vendor assembler (/usr/ccs/bin/as -V reports version
|
16 |
|
|
"Standard C Development Environment (SCDE) 5.0 12/08/89"). This
|
17 |
|
|
way GAS/i860 is tested against a known good assembler.

TODO:
|
20 |
|
|
- Relocation testing is basically non-existent.
|
21 |
|
|
- pst.d (pixel store) is the only instruction with no testcase.
|
22 |
|
|
- Some pseudo instructions need testcases (mov, all pfmov, etc.).
|
23 |
|
|
- More tests for dual instruction mode: check that dual mode has a
|
24 |
|
|
proper pair (FLOP/core) of instructions, and other error conditions.
|
25 |
|
|
- Most current testcases use the default AT&T/SVR4 syntax; a few simple
|
26 |
|
|
tests of the Intel syntax should be added to prevent bitrot (including
|
27 |
|
|
relocatable expression syntax, etc). Test file dual03.s uses Intel
|
28 |
|
|
syntax lightly (i.e., register names without '%' prefix).
