IIRC, arm (32b) linker can emit "range extending thunks" to help jump large distances. Not sure what to make of this report; I wouldn't have expected this GCC randconfig to generate code in any of the sections that were added to the linkerscript in https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eff8728fe69880d3f7983bec3fb6cea4c306261f.

Without this, 64-bit calls are limited to a 22-bit pc-relative offset (8 MB). This does make branches somewhat less efficient. At the moment, the 64-bit linker does not support adding branch extending stubs. Thunks are currently limited to a 17-bit pc-relative offset.

When using huge pages, I've tried to set up a lds layout in which all init functions are in one page which can be deleted afterwards. I assume that's why they can't be reached. I'll look into the issue if I can reproduce it. Will keep you updated.

The problem with this .config is, that both CONFIG_MODULES and CONFIG_MLONGCALLS are set to "n". The Kconfig autodetection needs fixing to enable CONFIG_MLONGCALLS in this case. This patch fixes it for me: [PATCH] Require -mlong-calls gcc option for !CONFIG_MODULES When building a kernel without module support, the CONFIG_MLONGCALL option needs to be enabled. This patch fixes the autodetection in the Kconfig script and uses a far call to preempt_schedule_irq() in intr_do_preempt().

The logic is: - if (!MODULES || UBSAN || FTRACE) then don't ask and always set to Y, - otherwise show menu entry but leave default as N. If this can be done in one line I'm happy to correct it.

"BL" is already using "b,l", see #define in arch/parisc/include/asm/assembly.h The 22-bit weren't sufficient, that's why I changed it too.

Okay but "b,l" only provides a 22-bit branch with %r2 as link register. You also need to use %r1 in the ldil and ldo instructions.

Argh. Yes. Didn't know. We have BL,%r25 in the same file. > You also need to use %r1 in the ldil and ldo instructions. Ok, will fix. Helge ^ permalink raw reply [flat|nested] 11+ messages in thread
