From 7db436325db821b400328563ed693b09f8c4c46c Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Wed, 11 Dec 2013 23:34:40 +0000 Subject: kbuild: Fix debugging info generation for .S files Change the debuging info generation flag in KBUILD_AFLAGS from '-gdwarf-2' to '-Wa,--gdwarf-2'. This will properly generate the debugging info for .S files when CONFIG_DEBUG_INFO=y. It seems current gcc does not pass a '--gdwarf-2' option on to the assembler when '-gdwarf-2' is on its command line (note the differece in the gcc and as flags). This change provides the correct assembler flag to gcc, and so does not rely on gcc to emit a flag for the assembler.
