Definition of uintptr_t in Rinterface.h
Hi,
I was recently pointed out that a definition in Rinterface.h can be conflicting
with a definition in stdint.h:
/usr/include/R/Rinterface.h has:
typedef unsigned long uintptr_t;
/usr/include/stdint.h has:
typedef unsigned int uintptr_t;
(when 32bit platform complete definition is:
#if __WORDSIZE == 64
# ifndef __intptr_t_defined
typedef long int intptr_t;
# define __intptr_t_defined
# endif
typedef unsigned long int uintptr_t;
#else
# ifndef __in...

Handling userland char ** pointers
I''ve been trying to get access to a userland string that''s behind a
second level pointer using DTrace, but I can''t seem to get it to work.
I started with the example on the Team DTrace Tips and Tricks slides:
trace(copyinstr(*(uintptr_t *)copyin(arg0, curpsinfo->pr_dmodel ==
PR_MODEL_ILP32 ? 4 : 8)));
And when I couldn''t get it to work, I started breaking it down into
smaller pieces to see what was going on at each step. Here''s the "C"
and "D" code:
--- pt.c ---
static int sz = sizeo...

[LLVMdev] Being able to know the jitted code-size before emitting
Hi everyone,
vmkit requires to know the size of a jitted method before emitting the
method. This allows to allocate the correct size for the method. The
attached patch creates this functionality when the flag SizedMemoryCode
is on.
In order to implement this functionality, i had to virtualize some
MachineCodeEmitter functions.
Is it OK to commit the patch?
Thanks,
Nicolas

Definition of uintptr_t in Rinterface.h
The problem is elsewhere - Rinterface.h guards the ultima-ratio fallback with HAVE_UINTPTR_T but that config flag is not exported in Rconfig.h. Should be now fixed in R-devel - please check if that works for you.
Thanks,
Simon

[LLVMdev] [llvm-commits] [PATCH][Compiler-rt] Windows implementation of mmap functionality in clear_cache_test and enable_execute_stack_test
Hi Ruben,
> I see I missed some curly braces. I also modified spacing a tiny bit.
Doesn't seem so. E.g. you have:
+ if ( !VirtualQuery(addr, &b, sizeof(b)) )
+ exit(1);
+ if( !VirtualProtect(b.BaseAddress, b.RegionSize,
PAGE_EXECUTE_READWRITE, &b.Protect) )
Add space after "if". Do not put spaces after "(" and before ")". Same
for other

Using uintptr_t to simplify pointer handling in libFLAC
Hi list,
I suppose we could use uintptr_t to simplify pointer handling in
libFLAC/memory.c.
The patch is attached. Passed build on gnu environment. Thanks.

Rconfig.h would be appropriate if Rinterface.h is being included from C
code using the same compiler as used for R. But as Rinterface.h is
