8f7669b247 1 - A few minor syntactic changes. 
2 - Altered the description of strings as initializers. (sequence of U1's).

e29ef2395a 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.

546bcee023 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}.

a9beb24998 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).

96da898a4a 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.

a69b503ad0 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.

5fd55904ec 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.

c08fe56b97 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.

ed3db93f56 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.

cfdc2ce05f 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.

845c92825a 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

3adba1b759 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).

ea6c20f5d1 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.

2aa5c6b7d9 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.

bbc3cb33cc 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.

1c36c470db 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?

925701dc62 When building the parameter list for a pf-call, the line number 
for the exchanges war remembered at the wrong time.
This caused:
	foo(3,'string')
to cause an external identifier for the string. Fixed.

385d7ffbd8 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.
