similar to: malloc/calloc/strdup and R's aequivalents

Hi, I have issue with Calloc : at the compilation step, gcc tells "error : syntax error before ')' token". When I use the classical C calloc... free, everything's fine. Here's the part of code : a = (double*) Calloc(*n,sizeof(double)); when i remove this line or replace it with the calloc, it's ok Hint : In the header file R.h, there's a line : /* for PROBLEM

Hi, it looks like a few users of calloc had their arguments backwards. I checked the other users and they seem fine.

I'm running R 2.10.0 under Mac OS X 10.5.8; however, I don't think this is a Mac-specific problem.

I am trying to write a C function to create a vector of integers that can be used by the R calling function. I do not know the size of the vector in the R calling function. (Well, actually, I have an upper limit on the size, but that is so large that R cannot allocate it. What I'm doing in the function is to do a sieving procedure, and the result will be small enough to fit into my

I am trying to implement some new alignment based optimisations in our target backend, and I am wondering if there a way a target can specify that 'malloc', 'realloc' and 'calloc' always return a pointer to memory that is aligned to a particular boundary? Related too, is it possible to specify that the stack pointer always points to memory which is aligned to a

Hi, When looking into the bug in https://llvm.org/bugs/show_bug.cgi?id=21421, I found a regression test in Transforms/InstCombine/malloc-free-delete.ll against me to directly fix it. The test is, define i1 @foo() { ; CHECK-LABEL: @foo( ; CHECK-NEXT: ret i1 false %m = call i8* @malloc(i32 1) %z = icmp eq i8* %m, null call void @free(i8* %m) ret i1 %z } According to

That commit was about converting a couple of malloc+memset to calloc, not about replacing messages in other parts.

> I think we can do such optimization with operator new, because new never returns null. This is incorrect in the case of `new (std::nothrow) ...` - the whole point of `(std::nothrow)` is to tell new that it should return NULL in case of failure, rather than throw an exception (bad_alloc). But the point here is not the actual return value, but the fact that the compiler misses that the
