From 854e981cc69bb93b49bdd052c8bc1dc744509f04 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Wed, 1 Feb 2006 03:06:25 -0800 Subject: [PATCH] uml: fix hugest stack users The C99 initialization, with GCC's bad handling, for 6K wide structs (which _aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3 vars. Workaround this. Note that .name = { '\0' } translates to memset(->name, 0, '->name' size) - I verified this with GCC's docs and a testprogram.
