Subject: at91sam7x: force inlining of all the UART ISR functions.
X-Git-Tag: 2.5.0~443
X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=2c8af54b2053cae5a6b5ff073cfd94606b21920a;p=bertos.git

at91sam7x: force inlining of all the UART ISR functions.

NOTE: this is not just an improvement (that is worth to be applied
anyway), it's also a workaround for a GCC bug
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41999): the compiler
corrupts the stack pointer and the frame pointer when calling functions
with at least one parameter inside ISR functions, declared with
__attribute__((interrupt)).
