Revert "rename '_poserror' to '__poserror'" 2022-07-24 18:14:21 +02:00
Christian Groessler
758d9466c0 rename '_poserror' to '__poserror' 
The old name could be non-conforming to the C standard. The new name
is definitely in the "implementation name space".

See issue #1796.

884f72637b Put the alignment decrement code back into posix_memalign(). 
Without that code, the function returns a very broken pointer.

216bb22b20 Added a special version of a function which uses an absolute addressing mode to access the zero page. 
The PCEngine needs such operands to be redirected to RAM page $20 explicitly.  Fixes #1482; fixes #1483.

rand() use XOR to break up unwanted pair correlation (#1107) 
* rand() use XOR to break up unwanted pair correlation

This form of rand() cannot return the same value twice in a row.
Two additonal EOR instructions produce a more even distribution of successive pairs.
see comments on #951

* rand.s document purpose of XOR

* suggested srand() optimization: zero fill unnecessary

* test to validate implementation of rand()

* srand() improving behaviour and adding startup test

* srand() with a tail call to rand() for better initial shuffle

* srand() can fall through to rand() instead of tail call

df015f4766 Adjusted tolower() and toupper() to https://github.com/cc65/cc65/pull/997 
For some reason or another both the author of the PR in question and its reviewers didn't notice that the two functions in question were totally overlooked.

ac4866c027 Made assert() send SIGABRT when an assertion fails. 
A signal handler can catch it, and do anything needed to make stderr work.

fc6a63a15e Avoid unintended file "shadowing". 
3d8c3a4948 caused an unintended "shadowing" of files in /libsrc/runtime by files in /libsrc/common. Therefore the files in question are renamed (again) in /libsrc/common to make the files in /libsrc/runtime "visible" again.

411a5a9483 Don't pass mode argument to open() from _fopen(). 
It isn't necessary, since paravirt.c has a default if the mode isn't
pushed onto the stack.
