Hi.
Back to this I noticed that ppc64le target build is broken due to:
g++ -fno-PIE -c -g -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions

which is caused by the 4 added optabs:
+DEF_INTERNAL_OPTAB_FN (VCOND, 0, vcond, vec_cond)
+DEF_INTERNAL_OPTAB_FN (VCONDU, 0, vcondu, vec_condu)
+DEF_INTERNAL_OPTAB_FN (VCONDEQ, 0, vcondeq, vec_condeq)
+DEF_INTERNAL_OPTAB_FN (VCOND_MASK, 0, vcond_mask, vec_cond_mask)
looking at the generator:
Breakpoint 6, gen_expand (info=0x7fffffffe160) at
/home/marxin/Programming/gcc/gcc/genemit.c:516
516 if (find_optab (&p, XSTR (expand, 0)))
(gdb) bt
#0 emit_c_code (code=0x7fa0f0 "{\n if (rs6000_emit_vector_cond_expr (operands[0],
operands[1], operands[2],\n\t\t\t\t operands[3], operands[4], operands[5]))\n DONE;\n else\n
FAIL;\n}", can_fail_p=false, name=0x7fa190 "vcondv4sfv4sf")
at /home/marxin/Programming/gcc/gcc/genemit.c:306

I get there due to:
B- │516 if (find_optab (&p, XSTR (expand, 0)))│
│517 { │
│518 gcc_assert (p.op < NUM_OPTABS); │
│519 if (nofail_optabs[p.op]) │

│521 } │
#define DEF_INTERNAL_OPTAB_FN(NAME, FLAGS, OPTAB, TYPE) \
nofail_optabs[OPTAB##_optab] = true;
#include "internal-fn.def"
Any hint what's bad? Note that x86_64-linux-gnu is fine.
Do I miss a target hook?
