tests/run-tests.py: Enable Arm inlineasm FPU tests if possible.

agatti · agatti · commit 1a8cf2833a2b · 2025-08-26T03:12:00.000+02:00
This commits lifts the unconditional restriction on inline assembler FPU
tests for the Qemu platform, and makes said restriction conditional to
the lack of an available floating point unit on the running platform.

The Qemu platform supported only emulated machines that could target up
to a Cortex-M3, so an ArmV7-M target that had no support for floating
point.  With the addition of MPS2_AN500 to the list of emulated targets
the range was extended to cover up to Cortex-M7, so a floating point
unit may possibly be available and thus able to run the FPU inlineasm
tests.

For that, the test runner was changed to detect the running architecture
when checking the target capabilities; if the target reports its
MicroPython architecture to be either "armv7emsp" or "armv7emdp"
(providing single-precision and double-precision floating point unit
support respectively) then the FPU-only inline tests are not put into
the blocked tests list.
