Generate coff files very compatible with vanilla linker. - . Understands coff debug directives. - -Here are the guidelines of the work I have done : - - . Encapsulate format dependent code in macros where it is possible. - . Where not possible differenciate with #ifdef - . try not to change the calling conventions of the existing functions. - I made one exception : symbol_new. I would be pleased to hear about - a better solution. (symbols.c) - . Extend the use of N_TYPE_seg seg_N_TYPE tables so that segments can - be manipulated without using their format dependent name. (subsegs.c) - . Write a function to parse the .def debug directives - . Write two small peaces of code to handle the .ln directive. - . In write.c try to move all the cross compilation specifics (md_..) to - format dependent files. - . Encapsulate the data structures using generic types, macros calls. - . Added too much code to resolve the complexity of the symbol table - generated. Most of the code deals with debug stuff. - . Create another makefile, shorter, cleaner. - . Create a config.gas shell script to mimic the gcc,gdb... configuration - mechanism. This reduce the complexity of the makefile. - . Isolate the format dependent code in two files - coff.c coff.h - aout.c aout.h - elf.c elf.h [ Not yet ;-] - . added a little stack management routine for coff in file stack.c - . isolate os specific flags in m- files - -If further development is planed on it is should solve the following problems : - - . Encapsulate DESC & OTHER tests in a macro call. I'm not aware - of their exact semantics. - . Clean up the seg_N_TYPE N_TYPE_seg naming scheme - . Try to remove as much reference to segment dependent names as possible - . Find a cleaner solution for symbol_new. - . Report the modifications on vax, ns32k, sparc machine dependent files. - To acheive this goal, search for \<N_, sy_, symbol_new and symbolS. - . Allow an arbitrary number of segments (spare sections .ctor .dtor .bletch) - . Find a way to extend the debug information without breaking sdb - compatibility. Mainly intended for G++. - . should it do something to generate shared libraries objects ? - -I have tested this code on the following processor/os. gcc-1.37.1 was - used for all the tests. - -386 SCO unix ODT - gcc-1.37.1, gas, emacs-18.55 - -386 Esix rev C - gas-1.37/write.s - -386 Ix 2.02 - gas, all the X11R4 mit clients - -386 CTIX 3.2 - xsol (X11R4 solitary game), gas - -68030 unisoft 1.3 - the kernel (V.3.2) + tcp/ip extensions - bash-1.05, bison-1.11, compress-4.0, cproto, shar-3.49, diff-1.14, - dist-18.55, flex-2.3, gas-1.37, gcc-1.37.1, gdb-3.6, grep-1.5, - kermit, make-3.58, makedep, patch, printf, makeinfo, g++-1.37.1, - tar-1.08, texi2roff, uuencode, uutraf-1.2, libg++-1.37.2, groff-0.5 - -68020 sunos 3.5 (no, not coff, just to be sure that I didn't - introduce errors) - gcc-1.37.1, gas, emacs-18.55, gdb-3.6, bison-1.11, diff-1.14, - make-3.58, tar-1.08 - -68030 sunos 4.0.3 (idem) - gas - -I would be glad to hear about new experiences - - Loic (loic@adesign.uucp or loic@afp.uucp) - |
