search for: allocsize

Hi all, I added support for the allocsize function attribute to our compiler (LDC), thinking that that would enable removal of function calls when the allocated memory is not used. For example: ``` declare i8* @my_malloc(i32) allocsize(0) define void @test_malloc() { %1 = call i8* @my_malloc(i32 100) ret void } ``` I thought the my_a...

From: Sylvain Gault <sylvain.gault at gmail.com> On some architecture, including my hardware, the function ExitBootServices may need to be called twice in order to successfully exit the boot services. As stated by the UEFI spec, the first call to ExitBootServices may perform a partial shutdown of the services. It seems that during this partial shutdown, the memory map can be modified, thus

Hi all, consider the following function from Core.cpp in LLVM 9.0.0: LLVMValueRef LLVMBuildMalloc(LLVMBuilderRef B, LLVMTypeRef Ty, const char *Name) { Type* ITy = Type::getInt32Ty(unwrap(B)->GetInsertBlock()->getContext()); Constant* AllocSize = ConstantExpr::getSizeOf(unwrap(Ty)); AllocSize = ConstantExpr::getTruncOrBitCast(AllocSize, ITy); Instruction* Malloc = CallInst::CreateMalloc(unwrap(B)->GetInsertBlock(), ITy, unwrap(Ty), AllocSize,...
