From 2c8571703a3aacfb09defc35c42c6250a6746d58 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 4 Feb 2015 13:05:50 +0100 Subject: malloc_simple: Return NULL on malloc failure rather then calling panic() All callers of malloc should already do error checking, and may even be able to continue without the alloc succeeding. Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in common/built-in.o when building the SPL, triggering this gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of using malloc_simple in the first place.
