Subject: Patch to support AMD64 Solaris 10
Date: Mon, 25 Oct 2004 17:48:00 -0000 [thread overview]
Message-ID: <Pine.LNX.4.61.0410251739090.3442@digraph.polyomino.org.uk> (raw)
This patch adds initial support for Solaris 10 on AMD64. The test results
(debugging both 64-bit and 32-bit binaries) are fairly similar to those
for unmodified GDB (built as 32-bit and debugging 32-bit binaries), though
as the prerelease operating system isn't yet fully reliable running the
GDB testsuite it's difficult to get full testsuite results for comparison.
The configuration is based on the existing IA32 Solaris support.
A limitation of this patch is that GDB needs to be built as a 64-bit
binary (configured with CC="gcc -m64": 32-bit compilation is the default
for this system) to work on AMD64 Solaris; GDB built as a 32-bit binary
doesn't work with this patch on AMD64 Solaris 10. The problem is that
there is a single target triplet and so a single GDB configuration, but
64-bit GDB should be using the functions in amd64-sol2-nat.c added by this
patch while 32-bit GDB (which in any case could only debug 32-bit
binaries, but the operating system does support plain x86 systems as well
as AMD64 ones, so such a GDB is desirable) should be using the functions
in i386v4-nat.c. Any comments on the best approach for having the single
configuration cleanly support being built as both 32-bit and 64-bit?
