[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC) This adds -no-opaque-pointers to clang tests whose output will change when opaque pointers are enabled by default. This is intended to be part of the migration approach described in https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9. The patch has been produced by replacing %clang_cc1 with %clang_cc1 -no-opaque-pointers for tests that fail with opaque pointers enabled. Worth noting that this doesn't cover all tests, there's a remaining ~40 tests not using %clang_cc1 that will need a followup change.

[OpenCL] Added addrspace_cast operator in C++ mode. This operator is intended for casting between pointers to objects in different address spaces and follows similar logic as const_cast in C++. Tags: #clang Differential Revision: https://reviews.llvm.org/D60193 2020-05-18 11:02:01 +01:00
[test] Add {{.}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.}} `, (variable/constant/alias) `= ` with `={{.}} `, or inserts appropriate `{{.}} `. 2020-12-31 00:27:11 -08:00			`//CHECK-LABEL: define{{.*}} spir_func void @_Z3barPU3AS1i`
