From eb3f2083f91fa2c48bad4c997f5d8a4378aaf04e Mon Sep 17 00:00:00 2001 From: Lucio De Re Date: Mon, 25 Jul 2011 13:45:44 -0400 Subject: [PATCH] build: define getcallerpc in u.h (fix for Plan 9 build) . By defining getcallerpc(x) as __builtin_return_address(0) here, it becomes possible to use the Plan 9 compatible form when compiling using GCC. The alternative is to add conditional compilation based on the compiler identity in "cmd/8g/gsubr.c" to distinguish between the two cases.
