The flag -enable-aa-sched-mi should do what you want you want in the MachineScheduler pass. If you want to do it in the selection DAG, there is a subtarget hook that might do it: TargetSubtargetInfo::useAA() LLVM won’t generate the schedule you want anyway for Intel core processors, but the alias analysis can be useful in general. -Andy On Dec 16, 2013, at 6:03 AM, Haishan <hndxvon at

> ... math errno ... I wouldn't recommend to anyone that they should rely on math errno (because I don't trust libraries to correctly support it). My goal here was to incorporate our existing support for it into the rest of what I'm trying to document. My understanding is that for clang this primarily controls whether or not we feel free to substitute intrinsics for recognized

Hi everyone, I have rhel 6.x 64-bit machine and I want to install llvm-3.3. clang-3.3. Can anyone share the download link for the rhel-6 compatible (rpm package)?

About ftrapping-math: I think we should eliminate ftrapping-math, a boolean option, because it overlaps with ffp-exception-behavior, a 3 valued option. Or we can keep it in the clang driver for compatibility, but it should be rewritten by clang driver into ffp-exception-behavior=ignore and ffp-exception-behavior=strict. There are various fields in llvm and/or clang that maintain Boolean

Hi, I compile a case (test.c) to get object machine file (test.o) using clang as follows: "clang -target arm -integrated-as -c test.c -o test.o" My clang version is 3.3 and debug build. //test.c int a[6] = {1, 2, 3, 4, 5, 6} int main() { a[0] = a[5]; a[1] = a[4]; a[2] = a[5]; } //end test.c Then test.dump is generated by using the objdump tool. //test.dump ldr r1, [r0, #20]

This is in response to Reid's and John's comments about intrinsics. The setting of the work is a project on reconfigurable processors using the Transport Triggered Architecture (TTA) <http://en.wikipedia.org/wiki/Transport_triggered_architecture>. For the compiler this means that the target architecture is not fixed, but rather an instance of a processor template. Different

That would be a bug in the newlib makefiles. :) Sorry for being obtuse. Yes, if there indeed is a bug, it is in the newlib build system. I was trying to compile newlib with llvm-gcc. The need for

Hello, I have noticed that Peter wanted to port newlib to syslinux project some time ago. It seems that the porting was not finished. Peter mentioned (http://syslinux.zytor.com/archives/2004-February/003168.html) that sucj job would require a lot of efforts. At the same time newlib is usually regarded as a "highly portable C-library". I am wondering what are the major

Hi Reid, I'll write a separate post about the intrinsics, but just a quick note about the CFLAGS issue.

Does anyone on this list have experience with newlib? I'm thinking of porting newlib to the COM32 environment, rather than trying to hack my own mini-libc. I just wondered if anyone had any idea of how well that would be likely to work, and/or how well newlib works from a code size standpoint... -hpa

Hi There, I am trying to build a cross-compiler for an architecture with MIPS like ISA. To begin with, I built a toolchain for MIPSr2 which uses: Clang-3.1 for preprocessing, compiling, optimizing; Binutils-2.22 for assembling and linking; Newlib-1.20.0 as the standard C library implementation. I modified the Clang Driver to use the correct binutils tools and linker scripts. Compiling Newlib with

I managed to compile newlib with llvm-gcc yesterday. That is, the machine independent part is now basically done, and the syscall part contains no-op stubs provided by libgloss. I haven't tested the port yet, but since newlib has already been ported to many architectures, I would be pretty surprised if there were any major problems. A couple of things I noticed when configuring newlib for

I'd be happy to transfer my code and a brain dump on where I was intended to go with it to anyone who'd be willing to take over the effort. The bottom line is that I just don't have time, nor do I expect to have any time during this year. -hpa
