; CPU description file generator for the GNU assembler testsuite. ; Copyright (C) 2000, 2001, 2009 Red Hat, Inc. ; This file is part of CGEN. ; See file COPYING.CGEN for details. ; This is invoked to build allinsn.exp and a script to run to ; generate allinsn.s and allinsn.d. ; Specify which application. ; Called before/after the .cpu file has been read. ; Called after .cpu file has been read and global error checks are done. ; We use the `tmp' member to record the syntax split up into its components. ; Methods to compute test data. ; The result is a list of strings to be inserted in the assembler ; in the operand's position. ; For a general assembler operand, just turn the value into a string. """unsupported assembler operand"; For a keyword operand, choose the appropriate keyword. ; OPS is a list of values, e.g. from an ifield. ;; If an ifield has, e.g., 2 bits (values 0,1,2,3) and the keyword ;; only has two values, e.g. (foo 0) (bar 1), then we can get ;; invalid requests, i.e. for ifield values of 2 and 3. ;; It's not clear what to do here, but it seems like this is an ;; error in the description file. ;; So it seems like we should flag an error for invalid requests. ;; OTOH, we're just generating testcases. So instead we just ;; flag a warning and cope by returning the first keyword in the ;; list. "WARNING: Invalid test data request for keyword "": "".\n"" Compensating by picking a different value.\n""""\\""""foodata""4""footext""-4""footext""4""foodata""-4"; Test data for a field is chosen firstly out of some bit patterns, ; then randomly. It is then interpreted based on whether there ; is a decode method. ; FIXME: need to run the decoder. ; no decode method "unsupported mode class";; Return N values for assembler test data, or nil if there are none ;; (e.g. scalars). ;; ??? This also returns nil for str-expr and rtx. ;; ??? "invalid hw-index type"; Given an operand, return a set of N test data. ; e.g. For a keyword operand, return a random subset. ; For a number, return N numbers. ; Given the broken out assembler syntax string, return the list of operand ; objects. ; Collate a list of operands into a test test. ; Input is a list of operand lists. Returns a collated set of test ; inputs. For example: ; ((r0 r1 r2) (r3 r4 r5) (2 3 8)) => ((r0 r3 2) (r1 r4 3) (r2 r5 8)) ; L is a list of lists. All elements must have the same length. ; Given a list of operands for an instruction, return the test set ; (all possible combinations). ; N is the number of testcases for each operand. ; The result has N to-the-power (length OP-LIST) elements. ; Given an assembler expression and a set of operands build a testcase. ; TEST-DATA is a list of strings, one element per operand. ;(display (list result sl td "\n")) "\t""\n"; Generate the testsuite for INSN. ; FIXME: make the number of cases an argument to this application. "Generating gas test data for "" ...\n""\t.text\n""\t.global ""\n"":\n"; Generate the shell script that builds the .d file. ; .d files contain the objdump result that is used to see whether the ; testcase passed. ; We do this by running gas and objdump. ; Obviously this isn't quite right - bugs in gas or ; objdump - the things we're testing - will cause an incorrect testsuite to ; be built and thus the bugs will be missed. It is *not* intended that this ; be run immediately before running the testsuite! Rather, this is run to ; generate the testsuite which is then inspected for accuracy and checked ; into CVS. As bugs in the testsuite are found they are corrected by hand. ; Or if they're due to bugs in the generator the generator can be rerun and ; the output diff'd to ensure no errors have crept back in. ; The point of doing things this way is TO SAVE A HELL OF A LOT OF TYPING! ; Clearly some hand generated testcases will also be needed, but this ; provides a good test for each instruction.
