From 96d60656162f1233624abc95cf627c26b89666ca Mon Sep 17 00:00:00 2001 From: aroben Date: Tue, 26 Jun 2007 00:43:56 +0000 Subject: [PATCH] Land pdevenv and supporting scripts/programs pdevenv is a script that will open an instance of Visual Studio that can compile multiple files in parallel, similar to make -jN. It uses the following scripts/programs to accomplish this: CLWrapper: Compiles to vcbin/cl.exe. Calls Scripts/parallelcl. parallelcl: Actually performs the parallel compilation by forking multiple instances of the Microsoft-supplied cl.exe. MIDLWrapper: Compiles to vcbin/midl.exe. Calls through to the Microsoft-supplied midl.exe. This avoids having to invoke perl for every invocation of midl.exe, which would be quite slow.
