From da654b74bda14c45a7d98c731bf3c1a43b6b74e2 Mon Sep 17 00:00:00 2001 From: Srinivasa Ds Date: Tue, 23 Sep 2008 15:23:52 +0530 Subject: signals: demultiplexing SIGTRAP signal Currently a SIGTRAP can denote any one of below reasons. - Breakpoint hit - H/W debug register hit - Single step - Signal sent through kill() or rasie() Architectures like powerpc/parisc provides infrastructure to demultiplex SIGTRAP signal by passing down the information for receiving SIGTRAP through si_code of siginfot_t structure. Here is an attempt is generalise this infrastructure by extending it to x86 and x86_64 archs.
