table.

em abb1fce8ff 1 - A few minor syntactic changes.
2 - Altered the description of strings as initializers. (sequence of U1's).

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.

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}.

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.

bal 68a6231d11 pem did not generate a register message for var-parameters of
array- or record type. The routine "treewalk" is modified.
It generates a register message for every var-parameter, even
if it has its noreg-flag set.

bal ebed9d4804 unlk a6 added to restr(). 1984-09-11 15:44:14 +00:00
keie 5895758914 Added ego, basic and callname conventions. 1984-09-10 17:34:04 +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
keie 4c265a7cc6 Initial revision 1984-09-03 13:49:40 +00:00
sater 2bf16c5b2f Variable nregvars had a name clash with the array nregvar[] in the
file tables.c. That was different in the 8'th character (!"#$%&'()_).
These variables should actually be static.
1984-08-23 17:07:53 +00:00
keie 0d48be448f We do not use the missing " trick anymore.
The root directory of the EM tree is in the name EM_DIR, the
root directory for tempfiles is in TMP_DIR.
All other path's are relative to EM_DIR.

keie f6b59970f6 The ACK tree on the vax has as default machine 'vax2'. 1984-08-23 13:27:14 +00:00
keie 1d463f136a The missing trailing " trick is now also used for TMP_DIR. 1984-08-23 13:26:44 +00:00
keie 773f0aa626 The ms_gto is added. This is a trick used to indicate procedures
jumped to with gto.

sater 3744019c53 increased MAXNODES in small memory mode 1984-08-23 12:25:24 +00:00
sater 5689e6ab64 Increased the amount of information passed through error routines
to printf. The routine badassert, running on a 2/4 machine lost it's
last argument on the way.
Anyone know of a better way to solve this problem?
