This change introduces $LK_ROOT/toolchain as an official installation
directory for toolchains, as well as a new script for conveniently
installing them there (versus manual GETs + untarring).
getting_started.md is updated to suggest its use.
On mac qemu, trying to use the physical timer does not seem to work, but
really the virtual timer is what you should be using most of the time,
especially when running under emulation.
This change updates the `help` console command to list the available
commands alphabetically, but only when we're not panicking. This makes
`help`'s helping more helpful.
Move common logic into a default routine in platform/power that other
platforms can reuse to implement the general default shutdown logic.
Add helper routines to print the cause.
Refactor the platforms that had substantial halt logic to reuse the
default implementation.
Initialize the uart by passing in the base and irq, as well as a flag
specifying if it's the debug uart and should directly put data into the
console buffer (if present).
Remove clang-13 from the build list, since it's not present in ubuntu
24.04.
If someone thinks this is an issue, please drop an email and we can see
about adding it back.
This change updates lk.code-workspace to specify
* editor.detectIndentation as false, as otherwise that overrides
the desired editor.tabSize setting.
* editor.insertSpaces as true, since spaces are preferred over tabs.
* editor.formatOnSave as false for C and C++ files, as - in the absence
of a .clang-format file - the clangd extension is likely to default to
choices that don't respect the local style.
Though using the named nmemonics is a generally better idea it has the
unforunate property of not working on older compilers. In this case,
these new registers are for the Sstic extension, which is new enough
that even reasonably recent compilers as GCC 12.1 doesn't understand it.
Fixes issue #410
This loads all sections specified by PE header at the correct memory
location, and executes the entry point function. Only the
OutputString function of text output protocol is implemented,
so the only application we can run is hello world.

Clang linker would remove apps section even though variable
insied it are marked as "used". Per clang doc, we need to add
"retain" attribute to prevent section gc.

Sadly this doesn't really work in all situations and only happens to
work with gcc + binutils for 32bit accesses, presumably because gnu as
replaces a literal 0 with wzr.
Clang doesn't understand it at all.
This reverts commit 6c14941dec.
When dumping_mode_regs() on a fault, avoid printing the stack beyond the
current page. This prevents exceeding the stack base and hitting a
guard page in the case the stack use is < 128 bytes.

Test: crash test, observe double fault fixed

For older compilers (gcc 7.5.0 in particular) avoid using
-mgeneral-regs-only to override the floating point switches, since it
doesn't seem to understand that switch.
Instead more properly add the floating point switches for a module or
source file compiled with float. More compatible with all compilers.
Was already added to arm64, but arch/arm hadn't picked up this feature
yet. Uncovered a few places here or there that wasn't marking code as
float/no-float, but this fixes a problem where newer compilers are
starting to sneak in vector code because they can.
Issue #406
It's just a test routine that's using floating point, but since nothing
in cmpctmalloc should be used in interrupt context, it should be okay to
mark this code as using float.
Some routines inside the sensor bus code in dartuino need floating
point, so put those in MODULE_FLOAT_SRCS.
Also mark app/accellerometer as needing float.
