I agree to follow the MicroPython Code of Conduct to ensure a safe and respectful space for everyone.
-
I've searched for existing issues matching this bug, and didn't find any.
Port, board and/or hardware
esp32/xtensawin and armv7emsp
MicroPython version
MicroPython 1.22.2 from git
Reproduction
- Have a dynamic native module using sinf/cosf functions
Note, you have to include the object files from libm and libgcc manually in the Makefile. This means extracting the .o files from the archives, and then adding them to SRC_O make variable. See this for an example:
https://github.com/emlearn/emlearn-micropython/blob/bd85ae1fade99b34a626c9fcaae0aa4f2ec87803/src/emlfft/Makefile
ifeq ($(ARCH), xtensawin)
LIBM_O := lib_a-sf_cos.o lib_a-sf_sin.o lib_a-ef_rem_pio2.o lib_a-kf_cos.o lib_a-kf_sin.o lib_a-sf_fabs.o lib_a-kf_rem_pio2.o lib_a-sf_scalbn.o lib_a-sf_floor.o
endif
ifeq ($(ARCH), armv7emsp)
LIBM_O := libm_a-sf_cos.o libm_a-sf_sin.o libm_a-ef_rem_pio2.o libm_a-kf_cos.o libm_a-kf_sin.o libm_a-sf_fabs.o libm_a-kf_rem_pio2.o libm_a-sf_scalbn.o libm_a-sf_floor.o
endif
ifeq ($(ARCH), armv7emsp)
SOFTFP_O := _arm_addsubdf3.o _arm_muldivdf3.o _arm_muldivdf3.o _arm_truncdfsf2.o
endif
ifeq ($(ARCH), xtensawin)
SOFTFP_O := _floatsidf.o _muldf3.o _divdf3.o _truncdfsf2.o
endif
- Try to build the module
Expected behaviour
Linking succeeds without errors, module is functional.
Alternatively: Error and/or documentation provides hints as to the possible reasons why this could happen, and ways of resolving.
Observed behaviour
Exception when linking. With ARCH=xtensawin
File "/home/jon/projects/micropython/tools/mpy_ld.py", line 572, in do_relocation_text
assert 0, r_info_type
AssertionError: 11
On ARCH=armv7emsp
File "/home/jon/projects/micropython/tools/mpy_ld.py", line 572, in do_relocation_text
assert 0, r_info_type
AssertionError: 2
