Assembly code macros not working #53

Open myan-o opened 5 months ago

myan-o commented 5 months ago

I have defined a macro in lib1funcs.S, but it seems that the macro is not visible in #include "ieee754-sf.S". It seems like there will be an error if it is commented out. If the file has a large number of characters, it seems to cause a macro undefined error. Is there a limit to the buffer size?

Assembler on its own doesn't support C preprocesor directives like #include. When you compile an assembly source file using GCC, there is an option to automatically run the source file through C preprocesor before passing it to the assembler. By default, GCC decides whether to do this or not based on the file extension. Assembly source files with .S extension are passed through the preprocesor, source files with .s extension are not. You can override this behavior using -x assembler-with-cpp option.

Where should I set it? If I set it to "CT_EXTRA_CFLAGS_FOR_BUILD" or "CT_EXTRA_CFLAGS_FOR_HOST", I get a syntax error when compiling test.c.

Are there instructions for building xtensa-esp32s3-elf?

igrr commented 5 months ago

Could you please describe what you are trying to do? What is the contents of test.c? What command are you running to compile it?

Even if the -x assembler-with-cpp option is specified, an error occurs.

It seems that the macro is not visible in #include "ieee754-sf.S".

If the file has a large number of characters, it seems to cause a macro undefined error. Is there a limit to the buffer size?

xtensa-esp32s3-elf is a part of xtensa-esp-elf toolchain. To build refer to .gitlab-ci.yml script https://github.com/espressif/crosstool-NG/blob/esp-1.26.x/.gitlab-ci.yml#L239-L247
