Hi Alex,
I finally came around converting some of my TriCore regression tests into actual
tests, that don't require the proprietary Infineon simulator.
These tests are heavily inspired by the riscv-tests [1]. I add macros that
allow easy testing of single asm instructions.
e.g. for add %d1, %d2, %d3 this looks like
insn test_num res rs1 rs2
v v v v v
TEST_D_DD(add, 1, 0x3, 0x1, 0x2)
Each of the macros generates code that loads the operands into registers,
executes the instruction, and finally checks if the result is as expected.
If the expected result does not match, a guest fail handler is called, that
writes the test_num to a testdev. This testdev takes the test_num and returns it
as an status code using exit(). If all tests pass, we jump to a pass handler,
that writes 0 to the testdev.
Unfortunately, I didn't add any switch to run this automatically on 'make check'
or similar, since there is no obvious way to integrate the tricore-binutils [2].
