A number of test cases assume that an "int" parameter or return value will be represented in the IR as a plain "i32" type. This causes the tests to spuriously fail on platforms where int is not a 32-bit type, or where the ABI requires attributes like "signext" or "zeroext" to be used. This patch adds -triple or -target parameters to force those tests to use the i386-unknown-unknown target. llvm-svn: 166551 2012-10-24 20:22:56 +08:00			`// RUN: %clang_cc1 %s -triple i386-unknown-unknown -emit-llvm -o - \| FileCheck %s`
Don't intentionally try to ignore the value of a scalar expression when we actually care about it. Fixes PR7291. llvm-svn: 105404 2010-06-04 03:58:07 +08:00			`// PR7291`

			`struct Foo {`
			`unsigned file_id;`

			`Foo(unsigned arg);`

			`{ }`

Revert "[CodeGenCXX] Treat 'this' as noalias in constructors" This reverts commit https://reviews.llvm.org/rL344150 which causes MachineOutliner related failures on the ppc64le multistage buildbot. llvm-svn: 344526 2018-10-15 23:43:00 +08:00			`// CHECK: define {{.}} @_ZN3FooC2Ej(%struct.Foo %this, i32 %arg) unnamed_addr`

IRgen: Assignment to Objective-C properties shouldn't reload the value (which would trigger an extra method call). - While in the area, I also changed Clang to not emit an unnecessary load from 'x' in cases like 'y = (x = 1)'. llvm-svn: 107210 2010-06-30 06:00:45 +08:00			`// CHECK: store i32 42, i32* %{{.*}}`
Fix a couple more tests with ARM ABI. llvm-svn: 133073 2011-06-16 02:37:44 +08:00			`// CHECK: ret {{void\|%struct.Foo}}`
