Fix -Wlarge-by-value-copy option handling in the driver. CC1 supports only the joined format. llvm-svn: 156161 2012-05-04 16:08:37 +08:00			`// RUN: %clang -### -Wlarge-by-value-copy %s 2>&1 \| FileCheck -check-prefix=LARGE_VALUE_COPY_DEFAULT %s`

Warn about -Wno-foo where foo is an unknown warning option. This is helpful for subtle misspellings such as -Wno-unused-command-line-arguments instead of -Wno-unused-command-line-argument. Also fix the diagnostic messages to properly handle -Wno- options. Previously, the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo). rdar://11461500 llvm-svn: 156937 2012-05-17 03:28:02 +08:00

[clang] Get rid of "%T" expansions The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in clang. Differential Revision: https://reviews.llvm.org/D36437 llvm-svn: 310950 2017-08-16 03:47:06 +08:00			`// RUN: %clang -### -c -target i386-apple-darwin10 -isysroot %t/warning-options %s 2>&1 \| FileCheck --check-prefix=CHECK-ISYSROOT %s`
Fix a regex error breaking tests. llvm-svn: 282004 2016-09-21 03:10:56 +08:00			`// CHECK-ISYSROOT: warning: no such sysroot directory: '{{.*}}/warning-options'`
