Member Function Documentation

void Module::AddExportedTypes ( const std::vector< std::pair< const Type *, SourcePos > > &  types)

Adds the given type to the set of types that have their definitions included in automatically generated header files.

Definition at line 1156 of file module.cpp.

References Error(), and exportedTypes.

void Module::AddFunctionDeclaration ( const std::string &  name,
const FunctionType functionType,
StorageClass  storageClass,
bool  isInline,
SourcePos  pos 
)

Add a declaration of the function defined by the given function symbol to the module.

We've got a declaration for a function to process. This function does all the work of creating the corresponding llvm::Function instance, adding the symbol for the function to the symbol table and doing various sanity checks. This function returns true upon success and false if any errors were encountered.

static

Compile the given source file, generating assembly, object file, or LLVM bitcode output, as well as (optionally) a header file with declarations of functions and types used in the ispc/application interface.

Parameters
srcFilePathname to ispc source file to compile
archTarget architecture (e.g. "x86-64")
cpuTarget CPU (e.g. "core-i7")
targetsTarget ISAs; this parameter may give a single target ISA, or may give a comma-separated list of them in case we are compiling to multiple ISAs.
generatePICIndicates whether position-independent code should be generated.
outputTypeType of output to generate (object files, assembly, LLVM bitcode.)
outFileNameBase name of output filename for object files, etc. If for example the multiple targets "sse2" and "avx" are specified in the "targets" parameter and if this parameter is "foo.o", then we'll generate multiple output files, like "foo.o", "foo_sse2.o", "foo_avx.o".
headerFileNameIf non-NULL, emit a header file suitable for inclusion from C/C++ code with declarations of types and functions exported from the given ispc source file.
includeFileNameIf non-NULL, gives the filename for the C++ backend to emit in an #include statement to get definitions of the builtins for the generic target.
Returns
Number of errors encountered when compiling srcFile.
