Macro Definition Documentation



LLVM_PLUGIN_API_VERSION Identifies the API version understood by this plugin.

When a plugin is loaded, the driver will check it's supported plugin version against that of the plugin. A mismatch is an error. The supported version will be incremented for ABI-breaking changes to the PassPluginLibraryInfo struct, i.e. when callbacks are added, removed, or reordered.

Function Documentation

◆ llvmGetPassPluginInfo()

::llvm::PassPluginLibraryInfo LLVM_ATTRIBUTE_WEAK llvmGetPassPluginInfo ( )

The public entry point for a pass plugin.

When a plugin is loaded by the driver, it will call this entry point to obtain information about this plugin and about how to register its passes. This function needs to be implemented by the plugin, see the example below:

return {
LLVM_PLUGIN_API_VERSION, "MyPlugin", "v0.1", [](PassBuilder &PB) { ... }
