e7e65044e6 Used more mundane addressing in some of the instructions in "zlib/inflatemem.s". 
That avoids conflicts with ca65's future .setdp feature.

32d000fb4c Fix broken rand() implementation. The high 8 bits were unused, reducing it to a 24-bit implementation (while still doing all the work for a 32-bit one). The best entropy is in the unused high byte, returning these bits in A instead of bits 8-15, which had considerably lower entropy (i.e. rand() & 255 was effectively a 16-bit LCG). 2016-07-11 20:48:47 -04:00

a6eb7d0763 Fixed how ca65 handles some debug info from cc65. 
ca65 used to claim that an assembler error/warning was found on a C code line; and, that an Assembly line is only indirectly related to it.
Now, ca65 says that the Assembly line has the problem; and, that the Assembly line was produced from the C line.

4014783275 Made the samples Makefile run cl65 only when we want a disk image. 
That change avoids an error message when we "make clean" from the top-level make-file (it removes the tools before it cleans the samples).

5d9f4dc89d Made the overlay demo programs compile for CBM targets again. 
<conio.h> includes target-specific headers; so, we didn't bother to include <cbm.h> where it is needed.  But, '#include <conio.h>' was removed from some files; so now, we must include <cbm.h> explicitly.

c9e9679a06 Improved doc and samples default target. 
The 'all' target deliberately doesn't build the doc nor the samples. But that doesn't mean that the Makefiles in the 'doc' and 'samples' directories must default to the (empty) 'all' target.

e47485f925 Added CONIO cursor support. 
For quite some time I deliberately didn't add cursor support to the Apple II CONIO imöplementation. I consider it inappropriate to increase the size of cgetc() unduly for a rather seldom used feature.

There's no hardware cursor on the Apple II so displaying a cursor during keyboard input means reading the character stored at the cursor location, writing the cursor character, reading the keyboard and finally writing back the character read initially.

The naive approach is to reuse the part of cputc() that determines the memory location of the character at the cursor position in order to read the character stored there. However that means to add at least one additional JSR / RTS pair to cputc() adding 4 bytes and 12 cycles :-( Apart from that this approach means still a "too" large cgetc().

The approach implemented instead is to include all functionality required by cgetc() into cputc() - which is to read the current character before writing a new one. This may seem surprising at first glance but an LDA(),Y / TAX sequence adds only 3 bytes and 7 cycles so it cheaper than the JSR / RTS pair and allows to brings down the code increase in cgetc() down to a reasonable value.

However so far the internal cputc() code in question saved the X register. Now it uses the X register to return the old character present before writing the new character for cgetc(). This requires some rather small adjustments in other functions using that internal cputc() code.
