* 4647 - support 64-bit Linux in CIKartik Agaram2018-10-013-16/+149
| | | | | | Generated 32-bit binaries are different on 64-bit. So let's compare them only on a 32-bit platform. And let's start also verifying their run-time behavior on Linux.

* 4638 - extract some common libraries from appsKartik Agaram2018-10-0110-647/+336
| | | | | | | I'm still trying to figure out what the defaults should be. At the moment you have to explicitly pass in every file you want loaded into the output binary. Maybe that control is a good thing. The examples need no libraries so far.

| | | | | | | | | | | Another sanity check. We don't really have a clear big picture yet. But I've now slapped on checks for all the issues I was worrying about. A more rigorous solution would be some sort of interval tree. We'd also need to track segments generated at translation time. We don't do that so far.

* 4633Kartik Agaram2018-10-011-2/+6
| | | | | | | Detect overlapping segments when loading SubX source code. This will start to become more of a risk as we start loading multiple files, juggling multiple segments, etc.

| | | | | | | | Start requiring a '-o' flag to designate the output binary when translating. Things currently get funky if you pass in multiple inputs, but that's ok. This is the first step to supporting multiple input files for a single output binary.

| | | | | When I started SubX I imagined that being able to write machine code directly was a feature. Now it's just a hole I haven't bothered closing yet.

* 4616 - fix subx/examples/ex7Kartik Agaram2018-09-295-12/+51
| | | | | | | | | It was broken since I added support for global variables, back on Sep 1. One other subtle thing I've improved is the name `looks_like_hex_int`. We can now distinguish in the pack-operands transform between ignoring 'foo' because it doesn't look like a number, and immediately flagging '0xfoo' as an error because it *should* be a number.

* 4614 - redo simulated RAMKartik Agaram2018-09-299-54/+101
| | | | | | | | | | | Now simulated 'Memory' isn't just a single flat array. Instead it knows about segments and VMAs. The code segment will always be first, and the data/heap segment will always be second. The brk() syscall knows about the data segment. One nice side-effect is that I no longer need to mess with Memory initialization regardless of where I place my segments.

| | | | | | | More calling convention tweaks. Use EBP to get consistently at parameters and locals. Always put the first function argument closest to EBP.
* 4515Kartik K. Agaram2018-09-241-1/+9
| | | | | New '--dump' commandline arg to incrementally print trace lines to stderr as they're emitted.
