From 5a9f5c60dae8d173e9e2f6da78499c046600e6ca Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Sun, 29 Apr 2012 23:40:06 -0500 Subject: Convert ALLOC_FAIL macro into a function This path is rarely (read: never) taken in any normal run of the code, so injecting the fprintf() call everywhere with the macro is a bit overkill. Instead, add a lightweight _alpm_alloc_fail() function that gets called instead. This does have a reasonable effect on the size of the generated code; most places using the macros provided by util.c have their code size reduced.
