This patch from Ralf Grosse Boerger makes debugging more comfortable.
With this patch it's possible to - determine the according source code line for each asm statement (objdump -dS) - determine the source code file for each asm statement (objdump -ddl) This isn't exactly trivial because cache_as_ram_auto.c gets compiled to assembly and converted by a perl script afterwards. This patch solves the problem - by extending cache_as_ram_auto.inc with debug information and line numbers - by correcting the perl calls (".text" --> "\.text") - by creating a disassembly with source code and line numbers. (ctr0.disasm and coreboot.disasm) There's one minor downside to the patch: A complete abuild run takes up around 1.6G instead of about 700MB now. But I'm sure this is quite reasonable for the benefits. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Please commit while this is being worked out.
