...ed about 18 months ago, so unless we’re willing to move our GCC version to 8.3 JUST as easily, this seems like a horrific double standard.

We need to build with -mno-pic to disable all uses of GP, as well as use a custom linker script to avoid collisions between klibc.so's and the executable's segments.

Commit 8418552 ("[klibc] ia64: Fix shared build") switched to the function descriptor-less ABI. However, when passing a function pointer to the kernel for signal handling, it always expects a descriptor, and -mno-pic does not set any ELF flags that the kernel could detect. Thus to fix this regression we must construct descriptors solely for passing to/from the kernel. Despite this,

Commit 8418552 ("[klibc] ia64: Fix shared build") missed this use of the GP register, although the code appears to have been dubious anyway, assuming the address of errno was the first thing pointed to by GP. --- usr/klibc/arch/ia64/vfork.S | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/usr/klibc/arch/ia64/vfork.S b/usr/klibc/arch/ia64/vfork.S index

Some distributions default to PIE for their compilers, which on sparc is passed on to the assembler. Since the behaviour of %hi/%lo changes under PIC to become GOT offsets, the current assembly files need adapting to not try to use a GOT offset as an absolute address. --- usr/include/arch/sparc/machine/asm.h | 15 +++++++++++++-- usr/include/arch/sparc64/machine/asm.h | 1 +
