Subject: [U-Boot-Users] [patch u-boot git 2/3] better ARM9 compiler options
Date: Fri, 18 Jan 2008 12:50:50 -0800 [thread overview]
Message-ID: <200801181250.50303.david-b@pacbell.net> (raw)
Update some ARM9 builds to pass the exact CPU to GCC, when the compiler
supports that specification. This stops pessimizing codegen, and removes
voluminous warnings about (no) interworking support from EABI compilers.
(Like CodeSourcery's ARM 2007q3 release.)
