Member Data Documentation

CC1Args

std::vector<std::string>* clang::CreateInvocationOptions::CC1Args = nullptr

If set, the target is populated with the cc1 args produced by the driver.

This may be populated even if createInvocation returns nullptr.

Diags

IntrusiveRefCntPtr<DiagnosticsEngine> clang::CreateInvocationOptions::Diags = nullptr

Receives diagnostics encountered while parsing command-line flags.

If not provided, these are printed to stderr.

ProbePrecompiled

bool clang::CreateInvocationOptions::ProbePrecompiled = false

Allow the driver to probe the filesystem for PCH files.

This is used to replace -include with -include-pch in the cc1 args. FIXME: ProbePrecompiled=true is a poor, historical default. It misbehaves if the PCH file is from GCC, has the wrong version, etc.

RecoverOnError

bool clang::CreateInvocationOptions::RecoverOnError = false

Whether to attempt to produce a non-null (possibly incorrect) invocation if any errors were encountered.

By default, always return null on errors.

VFS

IntrusiveRefCntPtr<llvm::vfs::FileSystem> clang::CreateInvocationOptions::VFS = nullptr

Used e.g.

to probe for system headers locations. If not provided, the real filesystem is used. FIXME: the driver does perform some non-virtualized IO.
