nvptx-tools: a collection of tools for use with nvptx-none GCC toolchains.
Home Page: https://gcc.gnu.org/wiki/nvptx
Archive for the defunct sourcerytools.com website and mailing list archives. The site is reachable at:
For nvptx-none toolchain testing, we're using nvptx-none-run to launch kernels on a 1 x 1 x 1 grid with 1 x 1 x 1 threads. We'd like to use cuCtxSetLimit(CU_LIMIT_STACK_SIZE) to increase the per-thread stack size from its tiny default value (1 KiB?).
Even though a cuCtxGetLimit(CU_LIMIT_STACK_SIZE) does acknowledge the value set, if this is set "too high", inscrutable errors (CUDA_ERROR_ILLEGAL_ADDRESS) may result from later cuModuleLoadData (?!) or cuLaunchKernel calls.
It is unclear how to safely maximize the per-thread stack size.
See the Something strange. Ignore it. code in nvptx-as.c.
As raised in http://mid.mail-archive.com/[email protected]:
I'm not sure if silently ignoring "strange" tokens is a good strategy?
Bernd agreed in http://mid.mail-archive.com/[email protected]:
I'd rather fail if anything unexpected is seen.
Dear All
I am trying to install GCCcorre 10.3.0 with modules (EasyBuild) and the installation looks for the file
nvptx-tools-20210115.tar.gz in this link https://github.com/MentorEmbedded/nvptx-tools/archive
Is that file no longer available?
Many thanks in advance
Regards

..., /tmp/nvptx-run, which may not be portable enough. On the other hand, the lock file really is meant to be system-wide. Perhaps use a lock backed by shm_open -- but that would have its own portability issues...
I'm trying to compile gcc-7.3.0 using nvptx-tools and get the following error:

My configure for gcc is this:
../gcc-7.3.0/configure \

--prefix=$install_dir
I not 100% sure this is an nvptx-tools issue, but it seems to me that g++ will always pass --64 as a standard flag to as and nvptx-tools/bin/as should be able handle it.
There is currently a dependency in nvptx-run on the CUDA runtime library (libcudart) just for the call to cudaDeviceReset. If that is that really necessary, is the a similar function in the CUDA driver library (libcuda), or can this function call be removed altogether?
This ld doesn't implement standard Unix ld semantics, where "options which refer to files, such as -l [...], cause the file to be read at the point at which the option appears in the command line, relative to the object files and other file options" (GNU Binutils 2.38 ld documentation).
Instead, this ld first collects all -l options:
..., makes them unique:
..., then reads all input files on the command line:
..., and then processes unresolved symbols:
I noticed that when nvptx-as spawns the ptxas process, the latter does still have the former's file descriptors open (in particular, the *.s input file), presumably due to missing 'close-on-exec' handling. I don't know if we can unconditionally use the e flag with fdopen, or manually have to set up FD_CLOEXEC etc.; see https://stackoverflow.com/questions/1643304/how-to-set-close-on-exec-by-default, for example.
Similar to #29 for :VAR_MAP and :FUNC_MAP (cf. https://gcc.gnu.org/PR100059),
nvptx-as must keep the order the same for the entries of newly added indirect-function map table, for which the new tag :IND_FUNC_MAP is used.
Cross ref: https://gcc.gnu.org/pipermail/gcc-patches/2023-November/635176.html
Draft patch – should work but needs a testcase, similar to #29 / commit 3f67564 and follow up commit aa3404a.

break;During installation, nvptx-none-ar and nvptx-none-ranlib are created as symlinks to the ar and ranlib binaries found in $PATH. (The intention is to re-use those of the GNU/Linux host system.)
This makes the installation tree non-relocatable to a different system. Maybe wrapper shell scripts should be used instead?
The nvptx-none-run.exp facilitates a setup where compiling a test and running the test is done on the same machine.
It would be good to have a .exp file that facilitates a setup where compiling a test is done on one machine, and running the test on another. Put differently, nvptx-none-run.exp is based on sim.exp. We want a similar file based on, say unix.exp.
As a start, we could split nvptx-none-run.exp into two parts, one that is specific to compiling tests, and another that is specific to using sim.exp.

From https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591154.html
In PR97348, we ran into the problem that recent CUDA dropped support for
sm_30, which inhibited the build when building with CUDA bin in the path,
because the nvptx-tools assembler uses CUDA's ptxas to do ptx verification.
...
Deal with PR97348 in the simplest way possible: when calling the assembler for
sm_30, specify --no-verify.This has the unfortunate effect that after fixing PR104758 by building
libraries with sm_30, the libraries are no longer verified. This can be
improved upon by:
- adding a configure test in gcc that tests if CUDA supports sm_30, and
if so disabling this patch- dealing with this in nvptx-tools somehow, either:
- detect at ptxas execution time that it doesn't support sm_30, or
- detect this at nvptx-tool configure time.
[ See also https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97348#c1 ]
Nvptx-as has a hardcoded default of sm_30.
Instead, it should use the sm version as specified by the .target line as default.
This makes nvptx-as robust against changes in default sm version in gcc.
Some ".alias" support in nvptx-ld would be useful due to the limitations listed below – and complete lack before PTX ISA 6.3 (CUDA 10). Namely:
https://gcc.gnu.org/pipermail/gcc-patches/2022-March/592127.html states:
Starting with ptx isa version 6.3, a ptx directive .alias is available.
Use this directive to support symbol aliases, as far as possible. […]
The alias support has the following limitations.Only function aliases are supported.
Weak aliases are not supported. […]
Aliases to weak symbols are not supported […]
At some point we may add support in the nvptx-tools linker for symbol
aliases, and define f.i. malias=ptx and malias=ld to choose between the two in
the compiler.
[...]
An example of where this support is useful, is the OvO (OpenMP vs Offload) testsuite. The testsuite passes already at -O2. But at -O0, there are errors in some c++ test-cases due to missing symbol alias support.
Likewise sollve_vv's alpaka_complex_template.cpp testcase, which also fails with -O0.
Hi, I am trying to build GCC trunk with support for OpenACC offloading to NVIDIA devices on a macbook pro with an NVIDIA GPU. I have CUDA Toolkit-7.5 and NVIDIA drivers installed. I also have gcc 5.3.0 installed (via Homebrew).
The installation of nvptx-tools chokes looking for wait.h. Perhaps OS X is "unsupported" for now, but it would be great to be able to use gcc and gfortran with OpenACC on OS X. Do you have any tips for work arounds? Here is the output of configure and make:

I don't think this is intentional?
[install]/nvptx-none/bin/{ar,as,ld,ranlib} are currently created as (absolute) symlinks to the [install]/bin/nvptx-none-[...] files, which makes the installation tree non-relocatable to a different system.
This is more a help question rather than a issue

Am I as is then able to compile C++ code with OpenAcc directives and produce a binary that can run code on CPU + GPU?
or is there more to install
I found https://gcc.gnu.org/wiki/OpenACC quite hard to read
please update autoconf/automake to more recent versions, probably together with an update of libiberty to the current status of binutils/gcc trunk.
..., and as such, if they're specified, they print nvptx-none-run instead of nvptx-none-run-single.
Also, the value passed for the --target option should be used for naming the installed files, instead of hard-coding that to nvptx-none.
We're including a copy of libiberty.
There is an (apparently non-fatal) error during configuration:
[...]
checking whether byte ordering is bigendian... no
checking for a BSD-compatible install... /usr/bin/install -c
/bin/bash: [...]/source-nvptx-tools/libiberty/../move-if-change: No such file or directory
checking for sys/file.h... yes
checking for sys/param.h... yes
[...]
To remove code duplication, and under the assumption that we can probably use "more standard" interfaces than libiberty's, maybe it's not actually hard to get rid of libiberty altogether? (It has not yet been assessed which libiberty interfaces we're actually using.)
The purpose of the nvptx-tools is to test a gcc toolchain generating code for a single threaded ptx interpreter. The interpreter is provided by the cuda platform. Part of this platform is ptxas.
This is no ordinary assembler, but one with different optimization levels (-O0 ... -O4), and different code generators (-ori/-noori), and the task to insert the missing instructions and annotations handling the convergence stack (ssy, .s postfix). Consequently, ptxas can be less stable than you'd like for an assembler.
Nvptx-as.c calls ptxas with -O0. The purpose here is to do a minimal verification of the ptx validity. The output of ptxas is thrown away (so there's no great value in spending time optimizing the generated code), and the ptx is compiled again in nvptx-run.c (here using the cuda runtime functions rather than ptxas). The default optimization setting in nvptx-run.c though is -O4. Presumably the intention here is to achieve the fastest execution possible.
My observation is that while ptxas sigsegvs (and equivalent failures in nxptv-run) are of interest to nvidia, they are usually uninteresting from the point of view of gcc code generation.
Typically, when encountering such a sigsegv in the gcc test suite, we manually:
and if we find that the sigsegv goes away when changing any of those parameters, we conclude it's a cuda bug, and move on (perhaps by xfailing the testcase or some such).
I wonder if it makes sense to automate this:
This would reduce testsuite noise, save time, and reduce the number of xfails (and xpasses when running with different ptxas flags or cuda versions).
This could be implemented as the new default behaviour, or we could add a --fallback switch to nvptx-as.c and nvptx-run.c.
Eventually we could warn against using cuda versions which are known to be buggy to the point that that this fallback scenario doesn't help.
