These SANE operations can sometimes return incorrect values for certain negative integers such as -2147483648 and -53021371269120 (numbers with at least 16 low-order zero bits in their two's-complement representation). To work around this, we now avoid calling FX2C or FX2L on negative numbers, generally by saving and restoring the sign separately. These workarounds are used in several of the new <math.h> rounding functions, and also for code that converts floating-point values to comp or long long. There are some places in SysFloat that should be patched similarly, so we may still hit this problem in certain situations until that is done. |

ORCALib
Libraries for the ORCA language suite (ORCA/C, ORCA/M, ORCA/Pascal) for the Apple IIGS
If you would like to make changes to this compiler and distribute them to others, feel free to submit them here. If the changes apply to the Apple IIGS, they will generally be approved for distribution on the master branch. For changes that retarget the library to generate code for a different platform, the project will either be forked or a new repository will be created, as appropriate.
The general conditions that must be met before a change is released on master are:
-
The modified library must compile under the currently released version of ORCA/M.
-
The various languages that make use of the library mush still pass their respective test suites, or changes to those test suites must also be submitted.
Contact support@byteworks.us if you need contributor access.
A complete distribution of the ORCA languages, including installers and documentation, is available from the Juiced GS store at https://juiced.gs/store/category/software/. It is distributed as part of the Opus ][ package.
