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`

[CodeGen] Apply 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments. * Adds 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments * Gates 'nonnull' on -f(no-)delete-null-pointer-checks * Introduces this-nonnull.cpp and microsoft-abi-this-nullable.cpp tests to explicitly test the behavior of this change * Refactors hundreds of over-constrained clang tests to permit these attributes, where needed * Updates Clang12 patch notes mentioning this change Reviewed-by: rsmith, jdoerfert Differential Revision: https://reviews.llvm.org/D17993 2020-11-17 07:04:55 +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* %{{.*}}`
