[comp.sys.nsc.32k] __builtin_alloca in gcc

ian@sibyl.eleceng.ua.oz.au (01/09/91)

The code to make __builtin_alloca work on the 32k (*without* my
function prologue kludge) appears to have made it into gcc version
1.38. I am just in the process of building it so I haven't actually
tested it. You need to make sure the EXIT_IGNORE_STACK is *not* defined
in the tm file.

Anyone using code based on my patches will find __builtin_alloca works
whether or not EXIT_IGNORE_STACK is defined, but it should be more
efficient if EXIT_IGNORE_STACK is *not* defined.
