keie 8958cb6faf Altered the test path lib/n_ack into the normal path ACK_PATH. 1984-10-05 15:07:47 +00:00
keie b5fa0675b6 Added a priority associated with each phase. Paths with the highest 
total priority have preference.
 1984-10-05 13:34:38 +00:00
keie 8e680a6467 1 - Added some debugging for linker flags. 
2 - Setting of NEEDS and RTS is moved to main.c.
3 - Added recognition of -Rphase:[-]number for dynamic priority setting.
 1984-10-05 13:31:40 +00:00
keie c4434ccbce 1 - Most flags used by ack itself are now also passed to the phases 
for recognition with mapflag.
2 - A few bugs are removed in connection with argument passing to the
    linker (unrecognized flags and libraries).
3 - The setting of RTS, HEAD and TAIL is done directly after the
    path determination for each file.
 1984-10-05 13:28:56 +00:00
keie 5376af0d04 1 - Added RCS identification. 
2 - Removed the default for compiler and error file pathname.
    These are now always supplied by the callee.
 1984-10-04 11:08:42 +00:00
keie 080555fffd Bug removed: the trailing zero at the end of a growstring was not 
explicitly written in doassign(trans.c).
Only luck kept the program together.
 1984-10-01 17:42:56 +00:00
em 2c4b17e464 Compile-time option GLOBAL_OPT defined. If set, the resulting 
peephole optimizer will be suitable for optimizing the output of
the global optimizer. In particular, it doesn't change the register
messages.
 1984-09-14 10:25:07 +00:00
keie c97e1a7bc2 1 - The prop keyword with is flags is now obsolete. Its function is 
taken over by several other keywords: stdin, stdout, prep, optimizer,
    combiner and linker.
2 - The search order is changed. First {EM}/lib/{M}/descr, then
    {EM}/lib/ack/{M}, finally {M}.
 1984-09-13 14:40:09 +00:00
keie c93761cadc The t_do bits are not set by this module. The t_next entry is used 
to see whether the scan for this phase is already done.
t_do is now set in add_inputs(files.c).
 1984-09-13 14:35:02 +00:00
keie aa4bae59e0 1 - The t_do flags is now set by add_inputs(files.c). 
2 - Recognize the fact that it is possible to start a combiner without
    input files.
3 - Removed -d flag. Overflow for -v (>2) now ends up in debug.
    -v may be followed by a number indicating the increment.
 1984-09-13 11:07:46 +00:00
keie 527726167a 1 - The outfile entry is only used when the output file must not be thrown 
away.
2 - If a combiner has no named input file (only libs+flags) then issue
    a warning message and make up a name.
 1984-09-13 11:04:00 +00:00
keie 3c300d3e1c No comment. 1984-09-10 16:51:02 +00:00
keie 8443ef3f8d Combiners (ego, linkers) now use a list of path's(ack.h) to indicate 
their input files.
Unmatched flags are now sent to the linker.
 1984-09-10 16:48:57 +00:00
keie 1188f0e810 1 - A transformation is succesfull when 
a - a stopsuffix is indicated and met,
    b - the last transformation is included in the transformation path.
2 - Maintains a 'cash' of best paths for all transformation to be executed.
 1984-09-10 16:46:13 +00:00
keie 1dba1f5328 The input file names of the linker are to be found in a different place. 1984-09-10 16:45:12 +00:00
keie 20100c69c7 1 - added keywords callname and outfile. See manual. 
2 - multiple combiners are allowed now.
3 - A different search mechanism is used for finding descriptor files.
 1984-09-10 16:42:55 +00:00
keie c504e2e22a 1 - callname recognition is moved to rmach.c. 
2 - The overall scheme is altered.
	first, all input files are processed until a combining phase is met.
	then, all the combining phases are executed, the resulting files
	are again processed until a combiner (or final) phase is met.
3 - The EM_DIR shell variable can be used to set ack's idea of the EM
    home directory.
 1984-09-10 16:37:11 +00:00
keie 31f96c6850 1 - The names of temporary files are now Ack'hex''unique'.'suffix'. 
'hex' is the pid of the current invocation of ack in hex.
    'unique' is a tail unique to this invocation.
2 - The outfile field is used to indicate default naming, can be ovrrriden
    by the -o flag.
3 - Added handling for phases with multiple inputs (ego, linker).
 1984-09-10 16:33:03 +00:00
keie 6eda6ac320 The role of the combiner is -partially- assumed by the linker. 
Linker arguments are now part of the transformation structure.
Temp file nameing is changed.
 1984-09-10 16:30:47 +00:00
keie 384bb7f6c4 Naming of the tempname is changed (see files.c). 1984-09-10 16:29:37 +00:00

 1984-08-03 13:16:59 +00:00
keie fe922d190d String initializer handling is changed. 
Strings are now considered to be sequences of xU1's.
No alignment is done before or after the string other than the
alignment done for names and segment type switches.

sater aa9d50ff5a The sequence: 
lin 100
  cal $foo

keie 166bccd1b5 Initial revision 1984-07-02 15:35:56 +00:00
sater e30825a5dd Fixed bug: after BRA instruction was optimized away the variable lastbra 
pointed to the instruction following. This could lead to anything,
including bus errors. Lastbra is now reset to 0.
Bug discovered at Philips PMDS by Hans de Vries. The fix is also his.
Actually the function cleaninstr should be rewritten.

 1984-06-21 13:13:10 +00:00
keie 3cc1077553 Ack assumed that files resulting from transformations 
would not need to be fed through a pre-processor.
This assumption proved false. Ack was altered and allows
use of a pre-processor on files produced by other passes.
