Joel E. Denny 82eeb7f9a7 [FileCheck] Implement -dump-input-context ... This patch is motivated by discussions at each of: * <https://reviews.llvm.org/D81422> * <http://lists.llvm.org/pipermail/llvm-dev/2020-June/142369.html> When input is dumped as specified by `-dump-input=fail`, this patch filters the dump to show only input lines that are the starting lines of error diagnostics plus the number of contextual lines specified `-dump-input-context` (defaults to 5). When `-dump-input=always`, there might be not be any errors, so all input lines are printed, as without this patch. Here's some sample output with `-dump-input-context=3 -vv`: ``` <<<<<< . . . 13: foo 14: foo 15: hello world check:1 ^~~~~~~~~~~ 16: foo check:2'0 X~~ error: no match found 17: foo check:2'0 ~~~ 18: foo check:2'0 ~~~ 19: foo check:2'0 ~~~ . . . 27: foo check:2'0 ~~~ 28: foo check:2'0 ~~~ 29: foo check:2'0 ~~~ 30: goodbye word check:2'0 ~~~~~~~~~~~~ check:2'1 ? possible intended match 31: foo check:2'0 ~~~ 32: foo check:2'0 ~~~ 33: foo check:2'0 ~~~ . . . >>>>>> ``` Reviewed By: mehdi_amini, arsenm, jhenderson, rsmith, SjoerdMeijer, Meinersbur, lattner Differential Revision: https://reviews.llvm.org/D82203		2020-07-10 11:02:10 -04:00
