Cc: Christopher Faylor Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" X-SW-Source: 2001-11/txt/msg00222.txt.bz2 Message-ID: <20011111110300.s_0_fFmA4RD6JAb6t-3Xa8TXWZHW_CTdSD9qPglq2Qs@z> The patch below adds SSE registers for cygwin target. The only missing code is an addendum to configure.in in order to check if CONTEXT_EXTENDED_REGISTERS is known in winnt.h header file. I asked about this in http://sources.redhat.com/ml/gdb/2001-11/msg00219.html but got no answers... But I never wrote any of these rules, and I even don't know how to regenerate configure from configure.in file ... For now, to test the patch, you will need to do a 'make clean' followed by a 'make "CFLAGS=-dHAVE_CONTEXT_EXTENDED_REGISTERS -gstabs+ -O1"' for instance. PS: I disabled flowed mode from my Eudora settings and hope that this will fix the problems existing in the latest patches I sent. Please ask me to send it again attached if this patch does not aply cleanly. PS2: Once this patch is in, I will send the next, i.e. the support of debug registers... DJ Delorie's idea was correct, this works like a charm (at least for me on a Win2000 box). ChangeLog entry: 2001-11-26 Pierre Muller * config/i386/tm-cygwin.h: Define HAVE_SSE_REGS if HAVE_CONTEXT_EXTENDED_REGISTERS is defined. * win32-nat.c: Define CONTEXT_DEBUGGER_DR that will also include extended registers if HAVE_SSE_REGS is defined. (mappings array): Add offset of extended registers. (thread_rec): Use new CONTEXT_DEBUGGER_DR macro.
