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

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

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

Memory Forensics of OpenSSH
Hello List,
One of my project needs memory forensics of OpenSSH. Here is a brief description of the problem:
I have a raw memory dump, and all of the kernel data structures (e.g., task_struct, mm_struct) have been figured out. Now, I want to retrieve the data structures (e.g., struct session_state) of an SSH process instance. Finding a session key (active_state->newkeys) could be an example.

How to set read.table variables to vectors?
The summary stats for the xin and yin variables below are correct. However,
if I use plot(xin,yin), an exception is thrown saying that "object xin is
not found."
Also, it is apparent that I can't successfully replace the x and y vectors
with values from xin and yin.
The four plots on one panel are showing but the range of x and y is only
[0,1], and therefore, it seems like an

[cfe-dev] Proposal: Enable BUILD_SHARED_LIBS=ON by default for debug build.
Hi Yin,
I second David's words. I use shared libs myself on debug builds, but
static builds with gold on a local disk is pretty feasible. Before I
used gold, I had to have 16GB of RAM on my laptop, now I need less
than 8GB for static builds.

[LLVMdev] Should remove calling NULL pointer or not
Hi John,
It seems the dereferencing a NULL pointer is undefined behavior but
Calling a function through a null pointer seems o.k.
If so , for this place, we need comment out the check.

[LLVMdev] Any plan to add MIN/MAX isd node?
Hi Duncan,
To use select, usually, there is a compare before select.
Presence of comparison will disable some opportunities to
optimize some code. Select and Compare is not associative
neither.
Thanks,
Yin

[LLVMdev] Should remove calling NULL pointer or not
Hi,
For a small case, that calls NULL pointer function. LLVM explicitly converts
It to a store because it thinks it is not reachable like calling undefvalue.
In InstCombineCalls.cpp:930
I think it is not a right approach because calling null pointer function
Will segfault the program. Converting to a store will make program pass
Silently. This changes the behavior of a program.

Hi Duncan,
Yes, exactly. However, we need define Opcode MIN/MAX
Into ISDOpcodes.h. Do you like to add those two definitions
Into the tree?

Yin

at the IR level LLVM already has pattern matching helpers for
identifying min/max idioms, here is part of a transform using
this, from InstructionSimplify.cpp:

Is there any relationship between IR instruction and execution time
Hi Matt,
Thanks you so much for the reply!
I've tried the llvm-mca, it is helpful.
I was wondering whether the llvm-mca support the assembly code for the ARM?
I cross-compile the test file for ARM like that: clang test.c -O2 -target
arm-linux-gnueabihf -static -S -o test.s
If I want to check the performance using llvm-mca, is there any option of
"-mcpu" for ARM ?
Thanks,
Yin

Migrating from Mysql to PostgreSQL
I tried to use ''rake db_schema_dump'' from old MySQL database and then
use ''rake db_schema_import'' to rebuild the database in PostgreSQL. The
issue here is that only some of tables can be imported successfully.
For example, in the dumped schema.rb:
create_table "profiles", :force => true do |t|
t.column "ticker", :string, :limit

Hi Yin,
MCA does support the –mcpu and –mtriple options. We have one arm test in llvm/test/tools/llvm-mca/ARM for a cortex-9, which is an Out of Order chip.
Hope that helps!
