Summary: The issue with the python path is that the path to python on Windows can contain spaces. To make the tests always work, the path to python needs to be surrounded by quotes. This change updates several configuration files which specify the path to python as a substitution and also remove quotes from existing tests.

; This file verifies the behavior of the OptBisect class, which is used to
|
|
; diagnose optimization related failures. The tests check various
|
|
; invocations that result in different sets of optimization passes that
|
|
; are run in different ways.
|
|
;
|
|
; This set of tests exercises the legacy pass manager interface to the OptBisect
|
|
; class. Because the exact set of optimizations that will be run may
|
|
; change over time, these tests are written in a more general manner than the
|
|
; corresponding tests for the new pass manager.
