Added more detail about file I/O limitations to the LIBC user documentation section of the CC8 manual. (What used to be the "stdio" section is now broken up into several sections at the same level.) check-in: 23f92ab553 user: tangent tags: trunk
Rewrote the "Inline Assembly in the Native CC8 Compiler" section in the CC8 user manual after learning more about its behavior and limitations. check-in: 573aba2f6a user: tangent tags: trunk
Documented the new ./configure --boot-tape-* options, and updated some of the other configuration option docs in check-in: f5a05c7790 user: tangent tags: trunk
Passing --disable-cc8-cross now effectively sets --disable-os8-cc8. That wasn't necessary before, since we were distributing a pre-built version of the native CC8, but now that we're building it from source, we need the cross-compiler to produce cc8.tu56. check-in: ff7ab04cc3 user: tangent tags: trunk
Updated to cover new CC8 work check-in: 1992d9b147 user: tangent tags: trunk
Moved the "TC08 vs TD8E" and "V3D vs V3F" text from the file to the wiki, and referenced it from the ChangeLog. check-in: 01e0bc0d69 user: tangent tags: trunk
Clarified the tail end of the concrete memory map example in the CC8 user manual. check-in: 3f8a6d035d user: tangent tags: trunk
Fixed a field/page confusion check-in: 4037a35485 user: tangent tags: trunk
Added a missing LOADER prompt in previous check-in: 7e3988ba1e user: tangent tags: trunk
Fixed up a confusing use of LOADER/G in the new Memory Model stuff in the CC8 user manual. check-in: 0b061209fc user: tangent tags: trunk
Decided to put the "1" back at the beginning of the addresses for the UDF ranges in the CC8 manual: it's a pretty good bet that the UDF will remain field 1 despite LOADER jiggery-pokery. check-in: d166926273 user: tangent tags: trunk
Changed all of the bare CRs in the output from the final stage of the OS/8 CC8 (CC2.SV) to CRLFs. This solves a problem where PIP couldn't read the input file correctly, preventing us from using os8-cp in ASCII mode to copy the CC.SB file out to examine it in a civilized text editor. check-in: 529c0ee697 user: tangent tags: trunk
Changed all uses of fprintf() in src/cc8/os8/p8.c that don't use printf() format specifiers to fputs() instead, saving 200 core memory locations due to the lower amount of stack manipulation required to call a straight function with a single parameter. check-in: 0b3919909f user: tangent tags: trunk
Major improvements to the Memory Model section of the CC8 user manual following more RTFMing and experimentation. check-in: 8a9fab096f user: tangent tags: trunk
Much more detail in the Memory Model section of the CC8 manual after spending some time RTFMing and trying to figure out how CC8 and the stack it's built atop (FORTRAN II, SABR, LOADER) lay things out in memory. check-in: e5dc02cc2d user: tangent tags: trunk
Documented the breakdown of Field 1 usage by CC8 check-in: f289a33de1 user: tangent tags: trunk
src/cc8/os8/ was using size-4 hard tabs to emulate size-8 hard tabs, causing ugly output when you TYPE CC.SB or HEADER.SB on the OS/8 side. Changed these to size-8 hard tabs. Also added a Vim modeline to the top of the file to ensure that Vim (at least) will preserve our intent here. check-in: e7dd3c2c38 user: tangent tags: trunk
Added a paragraph explaining the existence of TADI and such in CC8 output. check-in: 571e4b9d7f user: tangent tags: trunk
Fixed a bug introduced by [c20811f34c] affecting uses of printf "%d": the implementation wasn't passing "10" as the new radix parameter. It wasn't caught because CC8, being a K&R dialect, doesn't need or support function prototypes. check-in: a230f38ad3 user: tangent tags: trunk
Clarifications to poetnerd's recent additions to the CC8 manual check-in: 970e63c338 user: tangent tags: trunk
A few minor updates: Native compiler needs 20K; Added mention of the current state of the pre processor, I.E. it does have some support in both compilers, including #asm. check-in: b76c7b756c user: poetnerd tags: trunk
Improved the section on Optimization in the CC8 manual check-in: fbb5c3e12f user: tangent tags: trunk
Typo fix check-in: 35b5b4b6f0 user: tangent tags: trunk
Added "Predefined OPDEFs" section to the inline assembly section of the CC8 manual, documenting the op-codes CC8 predefines in SABR output. check-in: 4a52fc8c15 user: tangent tags: trunk
Fixed some nonstandard OPDEFs in the SABR code generated by CC8: its "MQA" is normally called "ACL", and its nonstandard "MQO" opcode is what's normally called "MQA". check-in: a96f0c5f20 user: tangent tags: trunk
sprintf() now returns -1 when it hits an unknown format specifier, as cppreference says it should. This is actually smaller than the prior code, which incorrectly returned the number of characters written so far and then failed to terminate the output string. cppreference doesn't say we should terminate the output string in this condition, but the error return is enough to clue the user in that they shouldn't use the output string. check-in: 7e5e3a226d user: tangent tags: trunk
Added note about "no heap/malloc" to the CC8 manual check-in: 47f3716a0e user: tangent tags: trunk
Comment typo fix check-in: 433b6f5813 user: tangent tags: trunk
Added %X support to CC8's sprintf(), now that %x means "lowercase hex." check-in: 99491648cd user: tangent tags: trunk
The CC8 LIBC's itoa() function now has a radix parameter, like the function of the same name common in Windows and DOS C compiler standard libraries. This also effectively exposes the previously internal itoab() function, itoa() basically acting as a wrapper for it for bases other than 10 and for positive values in base 10. That is, the only difference between the two is for negative values in base 10. check-in: c20811f34c user: tangent tags: trunk
Grammar and clarity pass on the CC8 user manual check-in: 650ad501b1 user: tangent tags: trunk
Merged the content of the "Known Bugs in the OS/8 CC8 Compiler" section of the CC8 manual down into the new LIBC reference. check-in: 6edb45e03f user: tangent tags: trunk
Markdown formatting fix check-in: ec6d43e1ec user: tangent tags: trunk
URL fix check-in: 681a96c67d user: tangent tags: trunk
Rewrote much of "The Native OS/8 Compiler" intro material in the CC8 manual to reflect the new os8-run world, free of a pre-built cc8.tu56 image. Also removed cc8-tu56-update, referred to by that section, since it's now replaced by media/os8/scripts/cc8-tu56.os8. check-in: b58ecf4ec5 user: tangent tags: trunk
Typo fixes check-in: 92d5c4b19e user: tangent tags: trunk
Added note about lack of %ld in CC8 sprintf() check-in: e25e988ef8 user: tangent tags: trunk
Collapsed some introductory material in the CC8 manual together to flow better, and change all "I" either to "we" where blame-sharing seems advisable or to the names of particular people where credit direction is required. :) check-in: 6ff36e09c3 user: tangent tags: trunk
Moved a sentence down to make the CC8 doc flow better. check-in: f9acd37731 user: tangent tags: trunk
The documentation for the way fopen() in CC8's LIBC treats file name extensions was wrong. It may *still* be wrong, but I think it's *less* wrong, at least. check-in: daa54b854a user: tangent tags: trunk
Documented xinit() in the CC8 user manual. check-in: 7bde4d409d user: tangent tags: trunk
Added the "Pointers Wrap Around" section to the CC8 manual and referred to it from each function documentation where relevant rather than repeat the warning about pointer wrapping and 4096 word field sizes. check-in: bc9432c9fe user: tangent tags: trunk
Documented LIBC's strstr(), fixed a bug in its implementation discovered while comparing that implementation to our C reference, and clarified the whole "0-terminated word string" vs "NUL-terminated character string" thing. check-in: 3f02d1675d user: tangent tags: trunk
Documented revcpy(), strcpy() and strcat() in CC8's LIBC. check-in: fe8674b377 user: tangent tags: trunk
Clarified matters related to the stock CC8 include files libc.h and init.h in the manual. check-in: 8a7bc70515 user: tangent tags: trunk
The cc8-tu56.os8 script was not copying CCR.BI to DSK:, as earlier CC8 systems did. This invalidates all of the CC8-based test exemplars yet again. Sigh. check-in: 904e54195b user: tangent tags: trunk
Moved the inline assembly and calling convention section of cc8-manual.doc down to be near the Memory Model section, where it better belongs. Lots of improvements to the text after the move. check-in: f1e351cfb8 user: tangent tags: trunk
Added proper documentation for printf() and friends to check-in: 6988e82dd0 user: tangent tags: trunk
Documented memset() and memcpy() in CC8 LIBC. check-in: 0663863c87 user: tangent tags: trunk
Several more LIBC functions documented check-in: 3441874c6e user: tangent tags: trunk
URL fix check-in: 25556d8455 user: tangent tags: trunk
