| * | 4763 - back to the 'trivial' crenshaw2-1 compiler | Kartik Agaram | 2018-11-23 | 3 | -2/+426 |
| | | | | | | This time I've ported (and test-driven) 'GetChar' and 'GetNum'. The new tests bring together our new testable interfaces for read() and exit(). | ||||

| | | | | | | Bugfix: I forgot about ELF segment offsets when implementing VMAs. Eventually segments grew large enough that I started seeing overlaps. | ||||

| | | | | | | | Let's start highlighting all global variables in Red. Assembly programming has a tendency to over-use them. They're a necessary evil, but we should minimize the number of functions that access them. | ||||

| | | | | | | Long-standing and long-copied typo has been messing with our exit status on test failures. | ||||

| | | | | | | There can be situations where a run is striding through a segment. Reduce the number of reallocations that reallocations that requires. | ||||
| * | 4749 - speed up tests | Kartik Agaram | 2018-11-18 | 1 | -8/+14 |
| | | | | | | | | When we implemented 'read' our apps went over 0x1000 bytes, so I grew the initial segment size. But that slowed down emulation because each test was reallocating all segments. Now we allocate small segments at the start, and grow them gradually as needed. | ||||

| | | | | | | | | | | We'll use a common stream data structure for input and output streams. Having separate types makes more sense in a more high-level language, where we have type checking and where functions for handling the different types are more concise. But in machine code the sweet spot is more toward fewer types. | ||||

| | | | | | | | Start injecting all dependencies in the Crenshaw compiler app. In the process I realized the non-fake code path of 'stop' had a bug. | ||||

| * | 4727 - commit to better 64-bit support | Kartik Agaram | 2018-10-27 | 2 | -18/+16 |
| | | | | | | | | I've started testing more regularly on 64-bit Linux, and I realize that the binaries actually now compare identical even on 64-bit. Why did I ever add that condition to CI? Seems to be working now on Travis. Let's start comparing now and see if the problem happens again. | ||||
