runtime: jump indirectly to longjmp on Xtensa by deadprogram · Pull Request #5677 · tinygo-org/tinygo

deadprogram · 2026-09-12T16:29:24Z

What this fixes

tinygo_longjmp in src/runtime/asm_xtensa.S ends with j longjmp. The Xtensa
J instruction holds an 18-bit signed offset, thus it reaches only 128 KB.

picolibc's setjmp.S puts longjmp in the plain .text group of the linker
script, while all TinyGo code goes into the .text.* group after it. In a large
program the two are more than 128 KB apart and the link stops.

ld.lld: error: relocation R_XTENSA_SLOT0_OP out of range: -217201 is not in
[-131072, 131071]; references 'longjmp'
>>> referenced by asm_xtensa.S:33

This came in with #5653, which added panic recovery on Xtensa.

How to see it

A small program links correctly, thus the smoke tests do not find this. The
example programs in the ESP smoke test are all below 15 KB.

A large program shows it. The examples/ap program in
tinygo-org/espradio is 494 KB of code
on xiao-esp32s3 and 530 KB on esp32-mini32. Both stop at the link step.

CGO_CFLAGS_ALLOW='-fno-short-enums' tinygo build -target=xiao-esp32s3 ./examples/ap/

The change

Load the address of longjmp from a literal and jump to it with jx. The
literal carries an R_XTENSA_32 relocation, which has no range limit.

The literal is placed by hand in the same section as the code. Automatic
literals go into a separate section, which this tree already records as a cause
of bad l32r offsets with LLVM 22 and lld. See the comments in
src/device/esp/esp32.S and src/device/esp/esp32s3.S. The same hand-placed
idiom is already used in targets/esp32-interrupts.S and
targets/esp32s3-interrupts.S.

The jump stays a jump. tinygo_longjmp has no entry instruction and runs in
the register window of its caller. A call4 or call8 would rotate the window
a second time and give longjmp bad arguments.

a8 is free in both ABIs. In the windowed ABI it becomes a0 of longjmp,
which longjmp overwrites at once from the jmp_buf. In the call0 ABI it is a
scratch register, and longjmp reads only a2 and a3.

Tests

make smoketest-esp passes.
TestESP32QEMU passes with Espressif QEMU, for print.go and recover.go.
testdata/recover.go on ESP32-S3 hardware gives output identical to
testdata/recover.txt.
The two espradio programs above link, and the complete espradio smoke test
passes on xiao-esp32c3, xiao-esp32s3 and esp32-mini32.
The relocation changes from R_XTENSA_SLOT0_OP to R_XTENSA_32, in the
windowed ABI and in the call0 ABI.

tinygo_longjmp ended with a j instruction, which reaches only 128 KB. picolibc puts longjmp in the plain .text group of the linker script, while all TinyGo code goes into the .text.* group after it. In a large program the two are more than 128 KB apart and the link stops with an out of range R_XTENSA_SLOT0_OP relocation. Small programs link correctly, thus the smoke tests do not find this. Load the address of longjmp from a literal and jump to it with jx. The literal carries an R_XTENSA_32 relocation, which has no range limit. Place the literal by hand in the same section as the code. Automatic literals go into a separate section, which this tree already records as a cause of bad l32r offsets with LLVM 22 and lld. See the comments in src/device/esp/esp32.S and src/device/esp/esp32s3.S. Keep the jump instead of a call. tinygo_longjmp has no entry instruction and runs in the register window of its caller. A call would rotate the window a second time and give longjmp bad arguments. a8 is free in both ABIs. In the windowed ABI it becomes a0 of longjmp, which longjmp overwrites at once from the jmp_buf. In the call0 ABI it is a scratch register and longjmp reads only a2 and a3. The recover test passes on ESP32 in QEMU and on ESP32-S3 hardware.

Tested on my xiao-esp32s3 board using the espradio repo's examples.
