Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
ptxgen is a simple IR compiler that generates PTX code in stdout with the
|
||
|
|
input NVVM IR files. It generates warnings, errors, and other messages in
|
||
|
|
stderr. When multiple input files are given, it links them into a single
|
||
|
|
module before the compilation, and generates a single PTX module.
|
||
|
|
|
||
|
|
ptxgen always links the libDevice library with the input NVVM IR program.
|
||
|
|
|
||
|
|
Before compiling the input IR, ptxgen will verify the IR for conformance
|
||
|
|
to the NVVM IR specification.
|
||
|
|
|
||
|
|
Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
The command-line options, except for the program name and the input file
|
||
|
|
names, are directly passed to nvvmCompileProgram without modification.
|
||
|
|
Each input NVVM IR file can be either in the bitcode representation or
|
||
|
|
in the text representation. Input file names and command-line options can be
|
||
|
|
interleaved.
|
||
|
|
|
||
|
|
For example,
|
||
|
|
|
||
|
|
$ ptxgen a.ll -arch=compute_50 b.bc
|
||
|
|
|
||
|
|
links a.ll and b.bc, and generates PTX code for the compute_50 architecture.
