If you have the string /usr/bin, prior to this patch it would not be quoted by our YAML serializer. But a string like C:\src would be, due to the presence of a backslash. This makes the quoting rules of basically every single file path different depending on the path syntax (posix vs. Windows). While technically not required by the YAML specification to quote forward slashes, when the behavior of paths is inconsistent it makes it difficult to portably write FileCheck lines that will work with either kind of path.

; Ensure that IR count remarks in the legacy pass manager work.
|
|
; What this test should check for:
|
|
; * Positive, nonzero sizes before/after for whole-module remarks
|
|
; (It's okay to have nonzero sizes in per-function remarks, since a function
|
|
; can be created/destroyed by a pass.)
|
|
; * Nonzero deltas
|
|
; * Sizes are being tracked properly across multiple remarks. E.g, if we have
|
|
; original_count_1, final_count_1, and
|
|
; original_count_2, final_count_2,
|
|
; Then original_count_2 == final_count_1.
|
|
|
|
; For these remarks, the "function" field in the YAML file doesn't matter.
|
|
; Each of the testcases work by combining the output remarks with the
|
|
; optimization record emit using -pass-remarks-output. This is done to prevent
|
|
; test flakiness wrt instruction counts, but also ensure that the output values
|
|
; are equivalent in both outputs.
