2021-05-01	decodetree: Extend argument set syntax to allow types	Richard Henderson	1	-0/+1
	Rather than force all structure members to be 'int', allow the type of the member to be specified. Reviewed-by: Luis Pires <luis.pires@eldorado.org.br> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2020-09-14	decodetree: Improve identifier matching	Richard Henderson	1	-0/+7
	Only argument set members have to be C identifiers, everything else gets prefixed during conversion to C. Some places just checked the leading character, and some places matched a leading character plus a C identifier. Convert everything to match full identifiers, including the [&%@&] prefix, and drop the full C identifier requirement.

2020-06-09	decodetree: Drop check for less than 2 patterns in a group	Richard Henderson	1	-0/+13
	While it makes little sense for the end product to have a group containing only a single pattern, avoiding this case within an incremental patch set is troublesome. Because this is expected to be a transient condition, do not bother "optimizing" this case, e.g. by folding away the group.

2020-06-08	decodetree: Allow group covering the entire insn space	Richard Henderson	1	-1/+1
	This is an edge case for sure, but the logic that disallowed this case was faulty. Further, a few fixes scattered about can allow this to work. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2019-08-19	decodetree: Allow !function with no input bits	Richard Henderson	2	-0/+11
	Call this form a "parameter", returning a value extracted from the DisasContext. Reviewed-by: Philippe Mathieu-Daude <philmd@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2019-03-12	decodetree: Properly diagnose fields overflowing an insn	Richard Henderson	4	-0/+20
	Previously this would result in an exception for shifting the field mask by a negative number. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2019-03-12	test/decode: Add tests for PatternGroups	Bastian Koppelmann	6	-0/+68
	This adds one test that supposed to succeed to test deep nesting of pattern groups which is rarely exercised by targets using decode tree. The remaining tests exercise various fail conditions.
