Here comes the right import of gcc-2.6.0.
1994-08-02 20:15:59 +00:00
Include the parent Makefile.inc so we get a proper BINDIR definition. As explained by: bde
1999-04-18 09:36:11 +00:00
.include "../Makefile.inc"
Man the lifeboats! Tie down the hatches! Red alert! Activate gcc-2.7.2.1! (the old cc has been tagged with "gcc_2_6_3_final" so we have a reference point in case of unforseen disasters...) This has the objc backend active, and I think I've managed to get the f77 f2c support through in one piece, but I don't know fortran to test it. A 'make world' change and libobjc commit will follow. If you normally do 'make -DNOCLEAN world', do not do so this time, I know it can fail with groff. This version of gcc makes a **LOT** more warnings on our kernel.

Don't use "GCCDIR" as the multiple inclusion protector. Subdir Makefiles may want to override GCCDIR and this gets in the way.

GCCDIR= ${.CURDIR}/../../../../contrib/gcc
Update bmake glue to build GCC 4.2. Also: Switch FreeBSD to use libgcc_s.so.1. Use dl_iterate_phdr to locate shared objects' exception frame info instead of depending on older register_frame_info machinery. This allows us to avoid depending on libgcc_s.so.1 in binaries that do not use exception handling directly. As an additional benefit it breaks circular libc <=> libgcc_s.so.1 dependency too. Build newly added libgomp.so.1 library, the runtime support bits for OpenMP. Build LGPLed libssp library. Our libc provides our own BSD-licensed SSP callbacks implementation, so this library is only built to benefit applications that have hadcoded knowledge of libssp.so and libssp_nonshared.a. When linked in from command line, these libraries override libc implementation.

Minor Makefile cleanup. Do not use Makefile variables named 'version' and 'target'. Latter is problematic in particular as apparently FreeBSD's bsd.prog.mk re-defines it under some circumstances. This causes an unexpected failures like -dumpmachine not working for cc while working fine for c++. Do not re-define IN_GCC in multipe places, it gets inherited from Makefile.in anyway.

Complete the integration of tbemd branch into head. TARGET_BIG_ENDIAN is now completely dead, except where it was originally supposed to be used (internally in the toolchain building). TARGET_ARCH has changed in three cases: (1) Little endian mips has changed to mipsel. (2) Big endian mips has changed to mipseb. (3) Big endian arm has changed to armeb. Some additional changes are needed to make 'make universe' work on arm and mips after this change, so those are commented out for now. UPDATING information will be forthcoming. Any remaining rough edges will be hammered out in -current.

I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working cases, I've kept it in for now. Added mips64e[lb] to make universe, so more kernels build. And I think this (finally) closes the curtain on the tbemd tree.

# This must go after the -I for cc_tools to resolve ambiguities for hash.h

Move -I of cc_tool/ before the GCCDIR ones. When I imported EGCS into contrib/egcs/ I failed to prune out egcs/gcc/cp/hash.h which is generated from gxx.gperf. Thus `cc1plus' wasn't using the hash.h we generated by cc/cc_tools/Makefile, but rather the one in egcs/gcc/cp/. When I imported contrib/gcc/ I did prune gcc/cp/hash.h. Unfortunately the GCC maintainers weren't smart on their file nameing and there is also a egcs/gcc/hash.h (name overloading does NOT work as well on the filesystem as in C++...). Due to the -I ordering we are were then picking up gcc/hash.h when compiling `cc1plus'.
