From d1261468875f4772898c4395880735784e651d91 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Sat, 8 Jan 2011 00:54:30 +0000 Subject: The FAST_STREAM_TRANSFERS compile time option has been removed due to lack of use and low cost/benefit ratio. Add GCC_FORCE_POINTER_ACCESS() macro use to the RingBuffer library header, to attempt to force GCC into producing more efficient code for manipulating the buffers. --- LUFA/ManPages/CompileTimeTokens.txt | 7 ------- 1 file changed, 7 deletions(-) (limited to 'LUFA/ManPages/CompileTimeTokens.txt') diff --git a/LUFA/ManPages/CompileTimeTokens.txt b/LUFA/ManPages/CompileTimeTokens.txt index b120617e0..70ad1a935 100644 --- a/LUFA/ManPages/CompileTimeTokens.txt +++ b/LUFA/ManPages/CompileTimeTokens.txt @@ -90,13 +90,6 @@ * by defining this token, reducing the compiled binary size.
