Hi Sean, Currently, I want to make one note for building LLVM/Clang for ARM, and the other one for testing. People who building LLVM/Clang on a ARM board which has no more than 1G memory, should make a swap partition and use gold to avoid oom. The other one is not so obvious. People who want to run test cases on ARM should build LLVM/Clang with "--with-abi=aapcs" option, this is an

Why at are the problems you ran into? (it will be easier to know where to put them the more you tell us about the nature of the problems) Also, I believe that GettingStarted.html is outdated in some parts, so a refresher is certainly in order. --Sean Silva On Thu, Sep 20, 2012 at 9:57 AM, 陳韋任 (Wei-Ren Chen) <chenwj at iis.sinica.edu.tw> wrote: > Hi all, > > While

I recommend you copy HowToAddABuilder.rst as a template and put everything you want to add in a new file HowToBuildOnARM.rst. Just write up all of the content that you want to add in that document, and then submit a patch to llvm-commits. At that point, we can then discuss where best to put it, or whether the content could be merged with another page. The important thing is writing up all of the

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.)

How about sending a patch which remove those obsolete code, and let others give comment? Cheers, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab,

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 Pawel, PTX already be replaced with NVPTX. However, PTX subdirectory still sit in lib/Target in 3.2 release. Do you think update the release tarball is a good idea? Also could you remove it from the trunk? Thanks. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

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

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
