2020-06-05arm.risu, thumb.risu: Add v8.2 DP and FHM insnsPeter Maydell
Add coverage for the v8.2 DP and v8.2 FHM insns in the Neon extension space. (We already had the v8.1 VQRDMLAH/VQRDLSH and the v8.3 VCADD/VCMLA, so this brings the risu coverage into line with what QEMU has implemented so far.)

2016-11-07Change mode directive of ARM risu filesJose Ricardo Ziviani
If different risufiles are managed by a single risugen (like thumb.risu, aarch64.risu, and arm.risu are managed by risugen_arm.pm) the mode directive identifies such operation by prepending the module name: thumb.risu - .mode arm.thumb aarch64.risu = .mode arm.aarch64 arm.risu = .mode arm Signed-off-by: Jose Ricardo Ziviani <joserz@linux.vnet.ibm.com> Message-id: 1478452528-13684-4-git-send-email-joserz@linux.vnet.ibm.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2011-02-11Document the .risu format in the READMEPeter Maydell
Document the .risu file format in the README, rather than in three duplicate comments in risugen, arm.risu and thumb.risu.
2011-02-11Specify thumb vs ARM in the .risu file rather than command linePeter Maydell
Add support to risugen for reading "directives" from the .risu config file as well as instruction patterns. Use this to allow the .risu file to specify whether it contains ARM mode or Thumb mode patterns, rather than forcing the risugen user to pass the correct command line argument for the .risu file being used.

2010-12-07Add support for user-defined constraints on instructions.Peter Maydell
Add support for user-defined constraints on instructions. These are written as an optional braced-block at the end of the instruction pattern. When present, they are evaluated when the instruction is generated and should return true if the values of the variable fields are OK, false if the generation should be retried with another random number. Note that there is not much sanity checking on what we are being asked to evaluate!
