When we added the VMX support we needed to change the size of ucontext which requires versioning with multiple implementations. So get|set|swapcontext require a version with VMX for the new version and without VMX for the old version (and smaller context). Each version requires a unique name (thus __CONTEXT_FUNC_NAME)Roland McGrath wrote:
I can't figure out why this is anything other than:The common code in the trunk has to have versions with/without VMX/Altivec plus the ENOSYS stub for pre GLIBC_2_3_3. Assuming the powerpc NO_FPU implementation is a simple subset of the powerpc ABI then we need to provide the same version symbols as the base powerpc ABI.
#define NO_FPU #include <sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext.S>
and the like, with appropriate #ifdef NO_FPU insertions in the trunk files.
Sorry, I haven't figured out how this answers my question.
