[CodeGenCXX] Convert some tests to opaque pointers (NFC) Conversion done using the script at https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34. These are tests where the conversion worked out of the box and no manual fixup was performed. 2022-10-06 12:12:57 +02:00			`// RUN: %clang_cc1 %s -triple=arm-unknown-linux-gnueabi -target-abi aapcs -emit-llvm -o - \| FileCheck %s`

[Clang] Set writable and dead_on_unwind attributes on sret arguments (#77116) Set the writable and dead_on_unwind attributes for sret arguments. These indicate that the argument points to writable memory (and it's legal to introduce spurious writes to it on entry to the function) and that the argument memory will not be used if the call unwinds. This enables additional MemCpyOpt/DSE/LICM optimizations. 2024-01-11 09:46:54 +01:00			`// CHECK: declare void @_Z3fooPv(ptr dead_on_unwind writable sret(%class.SMLoc) align 4, ptr noundef)`
