X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=40098e8cd7268535ba581b50af0304b7ecacbef5;p=clang

[libclang] Make c-index-test check CINDEXTEST_REMAP_AFTER_TRIAL environment variable,
which when set it determines the trial number after which the remapping of files should
take effect.
