Ayke van Laethem	777d3f3ea5	builder: free LLVM objects after use This reduces the TinyGo memory consumption when running make tinygo-test from 5.8GB to around 2GB on my laptop.	3 years ago
Ayke van Laethem	ef3b3c0d6a	transform: fix poison value in heap-to-stack transform In https://github.com/tinygo-org/tinygo/issues/2777, a poison value ended up in `runtime.alloc`. This shouldn't happen, especially not for well written code. So I'm not sure why it happens. But here is a fix anyway.	3 years ago
Damian Gryski	4b2edc9a26	compiler: move allocations > 256 bytes to the heap	3 years ago
Ayke van Laethem	ef8c1a187d	transform: allocate the correct amount of bytes in an alloca When I wrote the code originally, I didn't know about SetAlignment so I hacked a way around it by allocating [...]uintptr types. However, this allocates a few too many bytes in some cases. This commit changes this to only allocate the space that we actually need. The code size effect is mixed, but generally positive. The combined average is reduced by 0.27% with more programs being reduced in size than are increasing in size.	3 years ago
Ayke van Laethem	f24a93c51d	compiler, runtime: add layout parameter to runtime.alloc This layout parameter is currently always nil and ignored, but will eventually contain a pointer to a memory layout. This commit also adds module verification to the transform tests, as I found out that it didn't (and therefore didn't initially catch all bugs).	3 years ago
Ayke van Laethem	c466465c32	main: add -print-allocs flag that lets you print all heap allocations This flag, if set, is a regexp for function names. If there are heap allocations in the matching function names, these heap allocations will be printed with an explanation why the heap allocation exists (and why the object can't be stack allocated).	4 years ago
Ayke van Laethem	e7a05b6e74	transform: do not lower zero-sized alloc to alloca The LLVM CoroFrame pass appears to be tripping over this zero-sized alloca. Therefore, do what the runtime would do: return a pointer to runtime.zeroSizedAlloc. Or just don't deal with this case. But don't emit a zero sized alloca to avoid this LLVM bug.

Jaden Weiss	93961f9d41	fix incorrect starting value for optimized allocations in a loop	5 years ago
Ayke van Laethem	d905476231	all: refactor heap-to-stack transform into the transform package Also add unit tests. This is the first of several transformation (optimization/lowering) passes that I'd like to move to the new transform package. This separates the compiler from the optimizer. Also, it finally adds unit tests for the compiler, not just end-to-end compilation tests. This should improve robustness and should make it easier to change these transformation passes in the future. While the heap-to-stack transform is relatively simple, other passes are much more complex. Adding unit tests not only helps robustness over time, but also doubles as documentation as to what these transformation passes do exactly.	5 years ago
