From: David Brownell Date: Sun, 22 Nov 2009 23:50:24 +0000 (-0800) Subject: ARM11: macro cleanup X-Git-Tag: v0.4.0-rc1~442 X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=fa9b0e2167c295c1f0de349563b893540fc73cb0;hp=af7f6891e98d538eabcf137d89f28bf3406a4999 ARM11: macro cleanup Make this code look more like the rest of the OpenOCD code. - Use calloc() directly, not NEW() ... and fix some potential memory leaks while we're at it. - Remove FNC_INFO ... it's a NOP that just clutters things, and it's trivial for developers to add tracing as needed. - Replace FNC_INFO_NOTIMPLEMENTED with LOG_WARNING calls; ditto. And stop having those call sites wrongly succeed! - Waste less space with the CHECK_RETVAL() macro.
