3// Framework for the dimexpr-match tests.
4//
5// These tests show whether an expression of type like `float (*)[25]`
6// can be used in a context expecting a type like `float (*)[rand()]`.
7//
8// A test includes this header and defines the function `runTests`.
9// The `runTests` body is made with macros defined here.
10//
11// Normally, drive a test either from test.py or ./dimexpr-match-detail.sh.
12// Direct usage is for making small repro cases, while troubleshooting a problem.
13//
14// Direct usage is:
15//
16// compiler=gcc -x c # pick one
17// compiler=$fa
18//
19// test=dimexpr-match-c.cfa # pick one
20// test=dimexpr-match-cfa.cfa
21//
22// $compiler $test
23// ./a.out
24// ./a.out -cmd4skip | sed -E -n 's/skip.*\| *//p'
25//
26// Expect the above compiler invocation to report success.
27// Expect the first a.out invocation to print a mix of "done" and "skipped" messages.
28// Assume the second a.out invocation (through sed) prints several compiler CLI invocations. For each...
29// Expect that running the current compiler invocation reports an error.
30// So far, this is what dimexpr-match-detail.sh does.
31//
32// The macro logic in here is hard to read.
33// A specific test's TRY_COMPAT definition is easy to read.
34//
35// An error message from an unexpected rejection is hard to read, because the message blames a macro.
36// To diagnose one, first obtain the failing case's coordinates by ruuning:
37// $compiler $test -E -P -DEMIT_COORDS > temp.cfa # just preprocessor
38// $compiler temp.cfa # will fail, want message
39// Open temp.cfa and chase an error detail's line number, to find the failing code.
40// Look at the pragma-message above the failing line, and read off the failure's -D coordinates.
41// Isolate this case by running: ... copied from pragma message ...............................................................................................
42// $compiler $test -E -P -DEMIT_MINIMAL -DINCLUDE_MINIMAL -DARRANGEMENT__OPTIN -DARRANGEMENT_PTRPARM_---- -DCASE_MANUAL -DCASE_FORMATION_L=--- -DCASE_FORMATION_R=--- -DCASE_EQUALITY=-- > mycase.cfa # template
43// $compiler $test -E -P -DEMIT_MINIMAL -DINCLUDE_MINIMAL -DARRANGEMENT__OPTIN -DARRANGEMENT_PTRPARM_CALL -DCASE_MANUAL -DCASE_FORMATION_L=LIT -DCASE_FORMATION_R=LIT -DCASE_EQUALITY=NE > mycase.cfa # example
44// $compiler mycase.cfa
45// The content of mycase.cfa is easy to read.

158RULE macros define the expected outcome:
159Given a compiler's functionality level and a test case, do we expect the compiler to accept or reject the case?
160
161Group STA: Statically stable
162 - literal
163 - enumeration
164
165Group DYN: Dynamically stable
166 - parameter that is a constant
167 - static constant global
168
169Group UNS: potentially Unstable
170 - variable
171 - parameter that is a constant reference to constant
172 - function return
173 - extern constant (safe and annoying here; must be here if you can link it to something that changes)
174
175C rules
176 - Reject a pair from group STA if it has two different values
177 - otherwise, accept
178
179CFA "classic" rules (what CFA actually does, before Mike brings in CFA rules)
180 - same as C, except
181 - reject STA/non-STA crossing
182
183CFA rules ("preview" only)
184 - accept a pair from group STA if it has the same value
185 - accept a pair from group DYN if it is written out the same (e.g. refers to same variable)
186 - otherwise, reject
187 (notably, reject all group UNS)
188 (notably, reject any group crossing)
189
190The RULE_* definitions below encode the summary above into the test harness's format.
191This format is: tabled function to {ACC,REJ} from {STA,DYN,UNS}^2 x {EQ,NE}
