- Nuke and reinstall HomeBrew for macOS builds. Gets around the whole problem of stale links and conflicting packages installed in the GitHub macOS images. - macOS 12 and Ubuntu 20.04 officially deprecated. Ubuntu 20.04 will be removed from GitHub's runner images on 01 APR 2025. - .travis/deps.sh: Add mingw32 as a dependency target, enable MinGW64 32-bit builds. - Work around LTO bug on Ubuntu and macOS compilers, where LTO appears to miscalculate the number of bytes stored when using the default byte swapping 'for' loop. This is a workaround that uses compiler swapping intrinsics for well known sizes that appeases LTO. The alternative is to wait for a compiler fix, which is infeasible.
Open SIMH machine simulator
This is the codebase of SIMH, a framework and collection of computer system simulators.
SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.
The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
