Include of nonexistent file would cause segfault. Co-authored-by: Matej Kafka <[email protected]>
Otherwise libelf does not compile on Windows without MinGW, because it tries to use `ftruncate`, which is POSIX.
TODO: Polyfill POSIX APIs used in os_emulation
Emulate POSIX syscalls using the "Low-Level I/O" API provided by CRT, which closely matches the POSIX semantics. TODO: test this, especially check if errno values are POSIX

…edictor' - fence.i instrukction will now cause predictor to flush BTB rows and BHT states - Even instructions which are Not Taken are added into BTB and updated into BHT - Unconditional jumps now have a flag in BTB and do not trigger BHT - Added 3rd predictor widget with additional information not directly related to BHT and BTB - Added new statistic counting total encountered branch instructions and pipeline flushes - Restructured predictor and GUI code

…h off by presets The predictor configuration should be exactly defined for each present. Whench chnaged presets page should switch to the custom choice. The logic is implemented now. The switch2custom prevents its own (possibly infinite) recursion. The switch2custom calls are guarded by condition to check for the change. Because labda(s) with if statements are quite complex, they are moved to functions named descriptively. BHT computed parameters redundant update code has been unified into new function.

The peripheral memory ranges aliases at the high addresses (0xffxxxxxx -> 0xffffffffffxxxxxx) solve peripherals access from code compiled by internal assembler which can generate only 32-bit LI and LA pseudoinstructions (LUI/AUIPC + ADD). In the real operating system, the peripherals would be mapped to the kernel/upper half of address space as well. The solution is not elegant but allows to use template.S and other examples in XLEN=64 (RV64IMA) mode. Placement of peripherals under 2 GiB limit would be probably simpler but we have been inspired by SPIM and QtMips and usual 32-bit systems memory map organization.

This is an attempt to make navigation in the "New" dialog easier and allow its future expansion even with more configuration pages where tabs and tab top-level bookmarks are hard to navigate. Closes #150

Avoid using time every clock cycle when it is not needed.
Amortize running QTimer at max speed. Exit needs special handling because otherwise, the core will keep running. For gui, this will be hidden under clicking latency.
