From f2e292ce58ca07d9bbe3cad75f8baa35bd85964a Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 7 Feb 2007 21:41:02 +0000 Subject: push bytecode decompressor out through APIs. Now the bytecode reader api's look like this: ModuleProvider *getBytecodeModuleProvider( const std::string &Filename, ///< Name of file to be read BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer, std::string* ErrMsg = 0, ///< Optional error message holder BytecodeHandler* H = 0 ///< Optional handler for reader events ); This is ugly, but allows a client to say: getBytecodeModuleProvider("foo", 0); If they do this, there is no dependency on the compression libraries, saving codesize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34012 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Bytecode/Reader/Reader.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'lib/Bytecode/Reader/Reader.cpp') diff --git a/lib/Bytecode/Reader/Reader.cpp b/lib/Bytecode/Reader/Reader.cpp index 1ba79915e7..0f0cf5e6cd 100644 --- a/lib/Bytecode/Reader/Reader.cpp +++ b/lib/Bytecode/Reader/Reader.cpp @@ -1981,7 +1981,7 @@ void BytecodeReader::ParseModule() { /// and \p Length parameters. bool BytecodeReader::ParseBytecode(volatile BufPtr Buf, unsigned Length, const std::string &ModuleID, - Decompressor_t *Decompressor, + BCDecompressor_t *Decompressor, std::string* ErrMsg) { /// We handle errors by @@ -2016,6 +2016,9 @@ bool BytecodeReader::ParseBytecode(volatile BufPtr Buf, unsigned Length, // If this is a compressed file if (Sig == ('l' | ('l' << 8) | ('v' << 16) | ('c' << 24))) { + if (!Decompressor) { + error("Compressed bytecode found, but not decompressor available"); + } // Invoke the decompression of the bytecode.
