keie b294ab5042 The universal assembler has a bug that precludes use of .align 
in text segments, except as the very last command.
 1985-03-15 10:50:35 +00:00
em 9d0812746b The assembler proved to contain yet another bug. 
.align in text segments will not work for values that are
not a divisor of the gcd of the instruction sizes.
 1985-03-14 17:33:28 +00:00
em 9f203c9a17 Expressions are now always calculated in long. 
Some backends needed that.

keie bf3ba84e92 Adapted to 4-4. 1985-03-04 17:26:31 +00:00

instruction pointers.

tail_em.

keie d2a6847715 The previous version still assumed two-byte integers. 1985-03-04 15:33:28 +00:00
keie 2690f07cbd Incorrect alignment caused odd _end, which caused 
failures of malloc().
 1985-03-04 15:30:44 +00:00

garde 736a2d1022 Many things improved and extended 1985-03-04 13:42:38 +00:00
keie 9d7b94ba34 Adapted to a single cv for all machines. 1985-03-01 22:10:44 +00:00
keie 218f7ed718 Corrected a horrible typing mistake. 1985-03-01 20:08:45 +00:00
keie cb0b2e08cf 1 - At RREMOVE also check the stack set aside for coercions. 
2 - When coercions unexpectedly need stack of part of the
stakpattern, discontinue this option.
 1985-03-01 16:25:21 +00:00
keie c2a990768d The top of the stack, which is set aside for certain 
coercions is now saved with special routines.
This allows RREMOVE to check for registers.
 1985-03-01 16:20:13 +00:00
keie 36537eccc0 Also clear D1 (for static link). 1985-03-01 16:00:23 +00:00

these registers were killed.
 1985-02-26 16:31:38 +00:00
keie 408dacc2aa The stacking pattern for ldc C and 4 with highw(c)==0 was incorrect. 
The effect was that rand() from libcc/gen always returned
a 0.
 1985-02-19 13:41:30 +00:00
keie 445d52de66 Moved retar from ret.s to trp.s. 
trp.s needed it and is behind ret.s in the library.
When ret.s is loaded, it calls (via unknown) trp.s so
inclusion in trp.s should work.
 1985-02-17 22:31:10 +00:00
keie b82c00e153 Added a line for 
loc loc cuu $1==$1, because write.e contained the line
loc 2
loc 2
ciu
and the cg failed to translate.
 1985-02-17 22:03:44 +00:00
em bbfb511322 Added .align 2. Prevents end of bss to be odd. 
Especially important for malloc, it distinguishes between
odd and even word pointers.

                Now we clear the upper byte after the movb.
                This allows the %[1] to be added to the allocate.
