Hi Justin, I believe the PTX section in the link below need some love, updating "lib/Target/PTX" to "lib/Target/NVPTX" for example. Would you like to take a look? http://llvm.org/docs/CodeGenerator.html#the-ptx-backend Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here. I am compiling LLVM trunk on Gentoo (gcc 4.5.2), and I get error message below, --- make[4]: Entering directory `/nfs_home/chenwj/llvm-3.1/svn/build/tools/clang/lib/Frontend' llvm[4]: Compiling InitHeaderSearch.cpp for Release+Asserts build

Hi, How can I dynamically change the code generation optimization level (e.g., None) of a JIT in other to recompile a function with a new optimization level (e.g., Default)? Thank you. Best regards, Nurudeen.

In other words, this test case guarantee that pr1028 will not back again. If so, it will fail.

Hello, I want to compile MiBench by clang, and the target-ISA is armv4. The code generated using llvm-2.9, clang-2.9, and arm-linux-gcc (gcc version 2.95.2), simulator is sim-panalyzer 2.0.3 . I use these commends: $ clang -O3 -o hello.ll -c -emit-llvm hello.c $ llc -O3 -o hello.s -march=arm -mcpu=strongarm1100 hello.ll $ arm-linux-gcc -O3 -march=armv4 -mcpu=strongarm1100 -static

Use "-triple x86_64-none-linux-gnu" makes this test pass. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

hi,chen: thaks for your explaining,after reading it i have a few problems more. 1.in the sentenses of "X32: subl $-128, %eax" and "; X64: subl $-128," ,i do not know what means that in detail,these sentences were writen follow which language rules? 2.i want to write such a test:translate a *.ll(i.e:hello.ll) file to a *.c file(i.e:hello.c) with llc,then verify if the .c

Hello, Thank you very much for the pointers. I am are able to create new MDNodes, filled with some constants, and attach them to llvm instructions. However, the metadata map is not getting updated as expected. For example, instead of the expected new entry !n = metadata !{some values} we are getting !n = metadata !{null} Do you know what might be wrong? Do we need to enter the MDNodes into the

Hi all, While building/testing LLVM/Clang on ARM, I often have problems that are undocumented on the website. I would like to contribute my experience if possible so that others can benefit from it.

Thank you, Chen! The thing is that I know the Makefile to complete that task. But what I want to know the clang command that can do that. Since the makefile will generate a .ko file while I can use the clang command "-O3-emit-llvm" to generate a corresponding .bc file so the pass can be run on that. Any help? -- 祝好！ 甄凯
