Hi, Please consider the attached patch. It allows the "PC 0x??? in psymtab but not in symtab" warning to be "toggled off". The reason for this, is for whatever reason I get it heaps with my PPC Assembler code. There doesn't appear to be any obvious incantation to control it or prevent it when building the asm files, so i've given up trying. The attached patch retains the current behaviour, but if someone is being inundated by the warning, which happens when it occurs, they can turn it off, and at least continue debugging OK. Obviously finding out why it happens is far better, but i know nothing about dwarf debug information, or the psymtab or symtab stuff, so i'm not going to be productive in finding a better answer. This patch is against GDB 6.4 Steven J
