Yannis Huber	75bcbbe6d8	riscv: align stack and data sections to 8 bytes Alignment on 4 bytes can cause load/store address misalignment exceptions when loading/storing 64bit values on the stack.	4 years ago
Ayke van Laethem	b9cdfd9e9a	riscv: add bare-bones interrupt support This commit adds support for timer interrupts, replacing the busy loop that was used before. It is perhaps the most simple interrupt to implement and should serve as the basis for further interrupt support in RISC-V.	5 years ago
Ayke van Laethem	d441f0152f	riscv: use LLVM tools instead of GNU toolchain Now that we use LLVM 9, RISC-V support in LLVM has far fewer bugs and we can avoid the GNU toolchain. * replace GNU linker with lld * replace GCC with clang Additionally, RISC-V was promoted to stable so it can be enabled by default in CI.	5 years ago
Ayke van Laethem	2f932a9eee	riscv: fix heap corruption The .sdata and .sbss sections are created by the compiler, but were not present in the linker script. That means that the linker put them after all other data/bss section, which happens to be where the heap also resides. This commit adds the .sdata and .sbss sections to the linker script, which gets the blinky examples to work again on RISC-V.	5 years ago
Ayke van Laethem	c6255e4d0a	targets: explicitly mark the stack as NOLOAD This prevents it from being of type PROGBITS in lld 9, it should always be NOBITS. It should fix the following error in lld 9: ROM segments are non-contiguous	5 years ago
Ayke van Laethem	ffa38b183b	all: add HiFive1 rev B board with RISC-V architecture This page has been a big help in adding support for this new chip: https://wiki.osdev.org/HiFive-1_Bare_Bones	6 years ago
Ayke van Laethem	2523772b5d	arm: use the lld linker LLD version 8 has added support for armv6m: https://reviews.llvm.org/D55555 This means we can use LLD instead of arm-none-eabi-ld, eliminating our dependency on GNU binutils. There are small differences in code size, but never more than a few bytes.	6 years ago
Ayke van Laethem	62d74d8329	all: compile and link using clang, where possible	6 years ago
Ayke van Laethem	8402e84b6d	runtime: implement a simple mark/sweep garbage collector	6 years ago
Ayke van Laethem	bc9210b674	nrf: add micro:bit board	6 years ago
Ayke van Laethem	12298d23a7	all: move generic ARM bits into separate files	6 years ago
Ayke van Laethem	5b0aaf0d39	targets: clean up and unify linker scripts Especially arm.ld needed some cleaning up. Other than that, I've made sure the two linker scripts look similar where possible.	6 years ago
Ayke van Laethem	505b1f750d	all: generate interrupt vector from .svd file	6 years ago
Ayke van Laethem	76e77917d8	targets: move target-specific files to this directory	6 years ago
Ayke van Laethem	bfff0c33e4	Fix external globals This broke the allocator on ARM, and with that the blinky example.	6 years ago
Ayke van Laethem	f9f92de1c3	Add a test for the unicode package This massively increases .data size, possibly because loads of unused globals are included. I'll need to investigate what's going on here. For now, increase the RAM size for nrf chips (the nrf52 has 64kB of RAM).	6 years ago
Ayke van Laethem	0d1b7239c1	Assorted allocator fixes	7 years ago
Ayke van Laethem	e171f32493	Implement minimal bump pointer allocator Useful for MCUs, until a real garbage collector has been implemented.	7 years ago
Ayke van Laethem	b45ea2deb9	arm: Fix linker script stack section	7 years ago
Ayke van Laethem	f4ee774866	Set up a stack I forgot to actually set up a stack for the program but strangely it (mostly) worked - probably due to inlining.	7 years ago
Ayke van Laethem	a446b4de97	Be able to actually run the blinky example on an nRF runtime.Sleep() doesn't work yet so it prints a lot of data. Also, this depends on a small patch to nrfx.	7 years ago
