From 4c831d97bf065ae5d0fcba80b28e8396dfda7f39 Mon Sep 17 00:00:00 2001 From: Quentin Colombet Date: Wed, 15 Jan 2014 22:04:35 +0000 Subject: [LTO] Add a hook to map LLVM diagnostics into the clients of LTO. Add a hook in the C API of LTO so that clients of the code generator can set their own handler for the LLVM diagnostics. The handler is defined like this: typedef void (*lto_diagnostic_handler_t)(lto_codegen_diagnostic_severity_t severity, const char *diag, void *ctxt) - severity says how bad this is. - diag is a string that contains the diagnostic message. - ctxt is the registered context for this handler. This hook is more general than the lto_get_error_message, since this function keeps only the latest message and can only be queried when something went wrong (no warning for instance). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199338 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/lto/lto.cpp | 7 +++++++ tools/lto/lto.exports | 1 + 2 files changed, 8 insertions(+) (limited to 'tools') diff --git a/tools/lto/lto.cpp b/tools/lto/lto.cpp index a28257f6ab..3d58a577dc 100644 --- a/tools/lto/lto.cpp +++ b/tools/lto/lto.cpp @@ -193,6 +193,13 @@ lto_symbol_attributes lto_module_get_symbol_attribute(lto_module_t mod, return mod->getSymbolAttributes(index); } +/// Set a diagnostic handler. +void lto_codegen_set_diagnostic_handler(lto_code_gen_t cg, + lto_diagnostic_handler_t diag_handler, + void *ctxt) { + cg->setDiagnosticHandler(diag_handler, ctxt); +} + /// lto_codegen_create - Instantiates a code generator.
