Building an L1 cache bandwidth benchmark (e.g. STREAM triad-only, no OpenMP, with small arrays), with certain compilers (e.g. Clang), currently generates extremely inaccurate results (SimEng achieves much more bandwidth than...

readlinkat writes path in 256 byte chunks

1

The loop at the end of the `readlinkat` implementation writes the resulting path back to memory in 256 byte chunks: ``` for (size_t i = 0; i < bytesCopied; i...

Add missing auxilary variables to initial stack frame

1

The ELF loader is supposed to set various auxiliary variables in the initial stack frame, which are subsequently used by the libc runtime. We currently just set `AT_PAGESZ` (used by...

Recommend adding `-Werror` to build flags for CI, to help catch more issues (e.g. switch/case fall-throughs!). Possibly `-Wextra` too, though that one is debatable.

Consider the following instruction: ``` fmov d0, #1.0 ``` Some testing shows that SimEng is treating `d0` as both an input and output operand, indicating that the flags coming from...

We will need to add some sort of flag to to indicate that a request is already in flight.

Add framework for collecting hardware counters and other performance metrics

1

Simple things like IPC, stalls, flushes can easily be built into the core code (and currently are). We may want to consider exposing some interfaces that would enable third-party code...

It would be useful to be able to set `SIMENG_DEBUG=1` to enable printing tracing and internal state information to `stdout` (potentially with multiple levels of verbosity). This would be used...

Once the repository is public, we can auto-generate Doxygen docs and deploy to a GitHub pages site (or similar).
