From e80fa6de4ccc5c4851eab9fb941f9282d2e3eb16 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 24 Oct 2012 22:35:32 -0700 Subject: altos: Replace __critical usage with ao_arch_critical as needed sdcc offers __critical as a machine-independent way to block interrupts, but as gcc doesn't, we need to use a compiler-independent construct instead. ao_arch_critical has been around since the AVR port, but some old __critical usages remained. This fixes a bunch of random hangs when communicating with MM over USB or the radio as the various stdio loops were running without interrupts blocked between the test and the sleep.
