gpu_neon: fix some missing ebuf updates

[pcsx_rearmed.git] / deps / lightning / check / jmpr.tst

/*
This is a very simple check to a condition that on lightning 2.0.5
could cause an assertion on some backends, due to correcting a problem
with temporaries that could not be saved/reloaded due to being used only
in the hardware instruction, or being considered live for too long on the
lightning instruction, and that could not be reloaded after the jump target
(or after false/true target on conditional branches).

If this code in lib/lightning.c:_jit_update():

		    for (regno = 0; regno < _jitc->reglen; regno++) {
			spec = jit_class(_rvs[regno].spec);
			if (jit_regset_tstbit(mask, regno) &&
			    (spec & (jit_class_gpr|jit_class_fpr)) &&
			    !(spec & jit_class_sav))
			    jit_regset_clrbit(mask, regno);
		    }

were removed, this test case, on x86_64 would fail like this:

lt-lightning: lightning.c:305: _jit_get_reg: Assertion `regspec & 0x02000000' failed.
Aborted (core dumped)
