Core compiler is based on the gcc2 development tree from Aug 2, 1997, so
we have most of the
features found in GCC 2.8.
Integrated GNU Fortran compiler based on g77-0.5.22-19970929.
Vast improvements in the C++ compiler; so many they have
page of their own!
Integrated C++ runtime libraries, including support for most major
GNU/Linux systems!
New instruction scheduler from IBM Haifa which includes support for
function wide instruction scheduling as well as superscalar scheduling.
Significantly improved alias analysis code.
Improved register allocation for two address machines.
Significant code generation improvements for Fortran code on Alphas.
Various optimizations from the g77 project as well as improved loop
optimizations.
Dwarf2 debug format support for some targets.
egcs libstdc++ includes the SGI STL implementation without changes.
As a result of these and other changes, egcs libstc++ is not binary
compatible with previous releases of libstdc++.
Various new ports -- UltraSPARC, Irix6.2 & Irix6.3 support,
The SCO Openserver 5 family (5.0.{0,2,4} and Internet FastStart 1.0 and 1.1),
Support for RTEMS on several embedded targets,
Support for arm-linux,
Mitsubishi M32R, Hitachi H8/S, Matsushita MN102 and MN103, NEC V850,
Sparclet, Solaris & GNU/Linux on PowerPCs, etc.
Integrated testsuites for gcc, g++, g77, libstdc++ and libio.
RS6000/PowerPC ports generate code which can run on all RS6000/PowerPC
variants by default.
-mcpu= and -march= switches for the x86 port to allow better control
over how the x86 port generates code.
Includes the template repository patch (aka repo patch); note the new
template code makes repo obsolete for ELF systems using gnu-ld such
as GNU/Linux.
Plus the usual assortment of bugfixes and improvements.
