b132b5bc60 flash: add openocd settings to atsamd21 / atsamd51 2020-08-25 14:18:01 +02:00

Remove --no-threads from wasm-ld calls.
The bugs linked from the original addition of this flag are fixed:
https://bugs.llvm.org/show_bug.cgi?id=41508
or 'possibly fixed':
https://bugs.llvm.org/show_bug.cgi?id=37064#c8
since LLVM 8.0.1. TinyGo only support LLVM 9+, and as noted in the
original PR (#377), this can be removed when switching to 9.

Additionally, this flag was dropped from LLVM 11.

d606315515 builder: try to determine stack size information at compile time
For now, this is just an extra flag that can be used to print stack
frame information, but this is intended to provide a way to determine
stack sizes for goroutines at compile time in many cases.

Stack sizes are often somewhere around 350 bytes so are in fact not all
that big usually. Once this can be determined at compile time in many
cases, it is possible to use this information when available and as a
result increase the fallback stack size if the size cannot be determined
at compile time. This should reduce stack overflows while at the same
time reducing RAM consumption in many cases.

Interesting output for testdata/channel.go:

    function                                 stack usage (in bytes)
    Reset_Handler                            332
    .Lcommand-line-arguments.fastreceiver    220
    .Lcommand-line-arguments.fastsender      192
    .Lcommand-line-arguments.iterator        192
    .Lcommand-line-arguments.main$1          184
    .Lcommand-line-arguments.main$2          200
    .Lcommand-line-arguments.main$3          200
    .Lcommand-line-arguments.main$4          328
    .Lcommand-line-arguments.receive         176
    .Lcommand-line-arguments.selectDeadlock  72
    .Lcommand-line-arguments.selectNoOp      72
    .Lcommand-line-arguments.send            184
    .Lcommand-line-arguments.sendComplex     192
    .Lcommand-line-arguments.sender          192
    .Lruntime.run$1                          548

This shows that the stack size (if these numbers are correct) can in
fact be determined automatically in many cases, especially for small
goroutines. One of the great things about Go is lightweight goroutines,
and reducing stack sizes is very important to make goroutines
lightweight on microcontrollers.

39433a3553 compileopts: automatically add -g flag when including debug symbols
Debug information is often useful and there is no reason to include it
for Go code but not for C code. Also, disabling debug information should
disable it entirely, not just for Go code.

aa3481e06a avr: fix target triple
It was `avr-atmel-none`, which is incorrect. It must be
`avr-unknown-unknown`.

Additionally, there is no reason to specify the target triple per chip,
it can be done for all AVR chips at once as it doesn't vary like
Cortex-M chips.

The board is normally flashed with the MSD programmer. Debugging needs a

e69131c0d3 nrf: expose the RAM base address
The RAM base address is needed during SoftDevice initialization. So far,
the same magic value has been used in aykevl/go-bluetooth and in TinyGo,
but this should be configured in only one place.

This will have additional benefits in the future:

  * It is currently set to 0x39c0, which is around 14.5kB. Most nrf51822
    chips have only 16kB of RAM, so this is way too much for those
    chips.
  * LLD in LLVM 11 allows expressions in the MEMORY part of linker
    scripts, which will allow overriding the SoftDevice RAM area with a
    linker flag, which might come in handy.

9f4459cee1 arm: make FPU configuraton consistent
Eventually we might want to start using the FPU, but the easy option
right now is to simply disable it everywhere. Previously, it depended on
whether Clang was built as part of TinyGo or it was an external binary.
By setting the floating point mode explicitly, such inconsistencies are
avoided.

This commit creates a new cortex-m4 target which can be the central
place for setting FPU-related settings across all Cortex-M4 chips.

565ff99c31 gba: always use ARM mode instead of Thumb mode
This results in bigger code size, but it works around a bug in the
linker.

The issue starts with the problem that libraries (picolibc, compiler-rt)
were compiled as ARM and the rest as Thumb. This causes some blx
instructions to be inserted by the linker to call into these libraries.

Ideally we should fix the libraries to use Thumb mode instead, but that
requires some more extensive changes (including fixes to compiler-rt)
and it's just way easier to use ARM mode everywhere.

dd0fb1dd9a arm: use -fomit-frame-pointer
The frame pointer was already omitted in the object files that TinyGo
emits, but wasn't yet omitted in the C files it compiles. Omitting the
frame pointer is good for code size (and perhaps performance).

The frame pointer was originally used for printing stack traces in a
debugger. However, advances in DWARF debug info have made it largely
unnecessary (debug info contains enough information now to recover the
frame pointer even without an explicit frame pointer register). In fact,
GDB has been able to produce backtraces in TinyGo compiled code for a
while now while it didn't include a frame pointer.
