Go 1.27 jsonv2 pushes testdata/json.go beyond the LM3S6965 flash
budget. Keep coverage on larger emulated targets while skipping only the
too-small Cortex-M QEMU configuration.
Go 1.27 packages can emit stack probes on Windows amd64 and arm64.
Link the compiler-rt stack probe builtins and use compiler-rt for those
targets so these packages build.
Go 1.27 adds generic methods (golang/go#77273). golang.org/x/tools
go/ssa v0.42.0 does not instantiate them: objectMethod only applies
receiverTypeArgs and ignores method-level type parameters, so a call
such as (*math/rand/v2.Rand).N resolves to the abstract generic method
and its body reaches createConst with a type-parameter-typed zero
constant, triggering "panic: expected nil interface constant".
Upgrade golang.org/x/tools to v0.47.0, whose go/ssa returns nil from
MethodValue for generic methods and instantiates method-level type
parameters. No compiler changes are required.
Since x/tools v0.47.0 requires Go 1.25, raise the minimum supported Go
version from 1.24 to 1.25.

The interface lowering pass used a separate formatter for method
signatures. Same-named local aliases could therefore make distinct generic
methods compare equal. Reuse getTypeCodeName so interface checks preserve
type identity.
x/tools SSA names and go/types strings can preserve the source spelling of
type arguments, so aliases can make distinct instances collide. Use the
canonical type encoding for function names, synthetic local type owners,
instantiated named types, and method sets.
Add cases where same-named local aliases instantiate generic functions,
local types, and methods with float32 and float64. Record the current
collisions and incorrect results.
Go 1.27 introduced the //go:linknamestd directive, a standard-library
variant of //go:linkname that does not require importing "unsafe". The
iter package switched to it for referencing runtime.newcoro and
runtime.coroswitch, which caused "linker could not find symbol
iter.newcoro / iter.coroswitch" errors when building with Go 1.27.
Handle //go:linknamestd the same as //go:linkname, bypassing the unsafe
import requirement, and add test coverage in the pragma compiler test.

Modern golang.org/x/sys/unix (v0.36+) declares its linknames
detached from function declarations, e.g.:
func syscall_syscall(...)
//go:linkname syscall_syscall syscall.syscall
TinyGo's pragma parser only inspected function doc comments and
therefore missed these, producing link errors like:
undefined symbol: _golang.org/x/sys/unix.syscall_syscall
Extend parsePragmas to also walk the enclosing *ast.File's
free-standing comments for //go:linkname directives matching the
function's name. Function-attached directives still take
precedence. The existing 'unsafe' import gate is preserved.
Fixes#4395, #5365
STM32F4 and F7 share the same OTG FS IP but have no USB driver in
TinyGo. This adds a full device-mode driver covering CDC, HID, and
MSC with working examples.
- OTG FS has 4 physical EPs (0–3); virtual indices 4–7 fold onto
them via physEP() so the existing machine/usb API is unchanged
- F4 bypasses VBUS sensing via GCCFG.NOVBUSSENS; F7 uses the USB
voltage regulator + GOTGCTL B-valid override instead
- STM32F7 PLL_Q changed 2→9 to produce the 48 MHz clock required
by USB/RNG/SDMMC; CK48MSEL cleared to select main PLL as source
- HID and MSC descriptors remapped at init() to physical endpoint
addresses (EP2/EP1 for HID, EP2/EP3 for MSC)
- usb-storage example replaced machine.Flash with a FAT12 RAM disk
so the host mounts without reformatting
- MSC sendCSW sets queuedBytes before state transition to fix a
missed byte-count on the status phase
Treat panicState as a bitmask so a recovered panic during Goexit
can clear the panic bit while preserving the pending Goexit bit.
This removes the separate deferFrame Goexit field and restores the
previous defer frame size.
Top-level tests now run in goroutines, which puts stdlib tests on
TinyGo's default host goroutine stack. encoding/xml's depth-limit
test needs a larger stack on Linux and Darwin, so run just that
package with a larger stack while leaving the rest of the host stdlib
tests on the default stack.
The threads scheduler handled runtime.Goexit using the generic deadlock
path, which parked the current pthread forever. Add a scheduler-specific
goexit hook so it can remove the current task and exit the pthread while
ordinary blocking deadlocks still block.
Track main goroutine Goexit so the last remaining goroutine reports the
expected deadlock instead of letting the process exit successfully.
Expand the crash coverage with the Goexit cases covered by Big Go's
runtime tests.
Keep a pending Goexit separate from the active panic state so recovered
deferred panics do not cancel the original Goexit unwind. Goexit should
also ignore -panic=trap, since it is not a panic.
Wire testing.FailNow and SkipNow through runtime.Goexit, and run tests
and benchmarks in goroutines. This lets Goexit terminate the user
function without skipping test bookkeeping. Add Goexit/recover coverage
and enable crypto/ecdh in the Linux stdlib test list.
* wasm: patch wasm_exec.js and wasm_exec_node.js from Go 1.18+
Port this commit https://github.com/golang/go/commit/680caf15355057ca84857a2a291b6f5c44e73329 removing polyfills from `wasm_exec.js`, now the environment is expected to provide all the required polyfills.
`wasm_exec.js` now only provides stub fallbacks for globalThis.fs and globalThis.process.
All NodeJS specific code is now in a separate file `wasm_exec_node.js` with its required polyfills.
* feat: bump minimum node version to 22
Drops official support for NodeJS 18 for WASM by removing the provided polyfills in the `wasm_exec.js`.
Now the environment is expected to provide the polyfill if it is running on older NodeJS versions
The new minimum required version for WASM is NodeJS 22+.
* chore: removed wrong comment
`wasm_exec_node.js` no longer contains the polyfill for NodeJS 18
* Add LinkerFlavor so the odd pairing of COFF+Linux is possible (necessary for UEFI)
* But back bits of builder.go that were mistakenly removed
* Update compileopts/config.go

* runtime: fix ticker not stopping when Stop races with its callback
On the threads and cores schedulers, timer callbacks run concurrently
with user goroutines.
If Stop (or Reset) was called in the window after the node was popped
but before its callback re-added it, removeTimer would not find the
timer in the queue, so it would be re-added to timer anyway.
Track timers whose callback is currently running in a firing list, and
have removeTimer mark a firing timer as stopped so its callback does not
re-add it.
Also make the timers test drain robust: allow a possible in-flight tick
delivered concurrently with Stop to settle before draining the channel.

* runtime: fix Stop/Reset semantics when racing a firing timer callback
Address review feedback on the ticker Stop-race fix. On the threads and
cores schedulers a timer callback runs concurrently with user goroutines,
which left several problems:
- removeTimer reported a firing timer as successfully removed, so
Stop/Reset could return true even though the callback had already
started (wrong semantics, notably for AfterFunc). firingTimerStop now
returns a bool and removeTimer no longer hands the still-firing node
back to resetTimer.
- The periodic advance (when += period) ran in timerCallback outside the
scheduler timer lock. Move it into each scheduler's reAddTimer, under
the lock and after the stopped check, so a concurrent Reset can't have
its freshly-queued deadline corrupted.
- resetTimer now sets when/period after removeTimer for the same reason.
Add testdata/timer_stop_reset_race.go and TestTimerStopResetRace, which
reproduce the stop-while-firing and reset-while-firing races via the
runtime timer linkname hooks.

A SHT_NOBITS section was unconditionally treated as .bss (RAM) unless it
was the stack. The ESP linker scripts emit non-writable SHT_NOBITS
sections (.irom_dummy / .rodata_dummy) that merely reserve the
flash-mapped XIP virtual address ranges and occupy no RAM. Counting them
inflated the reported bss/RAM usage.

Having them as methods on reflectlite.Value makes them
visible to the user.
Also move new functions out of all_test.go so it can stay
closer to upstream (except for comments).
