|
|
Revision 1.1 1999/05/01 13:23:57 peter
|
|
* merged nasm compiler
|
|
* old asm moved to oldasm/
|
|
|
|
Revision 1.14 1999/04/16 11:49:48 peter
|
|
+ tempalloc
|
|
+ -at to show temp alloc info in .s file
|
|
|
|
Revision 1.13 1999/03/12 00:20:03 pierre
|
|
+ win32 output working !
|
|
|
|
Revision 1.12 1999/03/11 17:52:34 peter
|
|
* fixed wrong ot_signed generation in insns tab
|
|
|
|
Revision 1.11 1999/03/10 13:41:07 pierre
|
|
+ partial implementation for win32 !
|
|
winhello works but pp still does not !
|
|
|
|
Revision 1.10 1999/03/08 14:51:05 peter
|
|
+ smartlinking for ag386bin
|
|
|
|
Revision 1.9 1999/03/06 17:24:18 peter
|
|
* rewritten intel parser a lot, especially reference reading
|
|
* size checking added for asm parsers
|
|
|
|
Revision 1.8 1999/03/05 13:09:50 peter
|
|
* first things for tai_cut support for ag386bin
|
|
|
|
Revision 1.7 1999/03/03 11:41:53 pierre
|
|
+ stabs info corrected to give results near to GAS output
|
|
* local labels (with .L are not stored in object anymore)
|
|
so we get the same number of symbols as from GAS !
|
|
|
|
Revision 1.6 1999/03/03 01:36:44 pierre
|
|
+ stabs output working (though not really tested)
|
|
for a simple file the only difference to GAS output is due
|
|
to the VMA of the different sections
|
|
|
|
Revision 1.5 1999/03/02 02:56:18 peter
|
|
+ stabs support for binary writers
