From 464b4b66e3cf3b5489e730c1466ee1bf825560e0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dan=20Hor=C3=A1k?= Date: Mon, 31 Jan 2022 14:08:09 +0100 Subject: powerpc64: fix handling of homogeneous float128 structs (#689) If there is a homogeneous struct with float128 members, they should be copied to vector register save area. The current code incorrectly copies only the value of the first member, not increasing the pointer with each iteration. Fix this. --- src/powerpc/ffi_linux64.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src') diff --git a/src/powerpc/ffi_linux64.c b/src/powerpc/ffi_linux64.c index 4d50878..3454dac 100644 --- a/src/powerpc/ffi_linux64.c +++ b/src/powerpc/ffi_linux64.c @@ -680,7 +680,7 @@ ffi_prep_args64 (extended_cif *ecif, unsigned long *const stack) { if (vecarg_count < NUM_VEC_ARG_REGISTERS64 && i < nfixedargs) - memcpy (vec_base.f128++, arg.f128, sizeof (float128)); + memcpy (vec_base.f128++, arg.f128++, sizeof (float128)); else memcpy (next_arg.f128, arg.f128++, sizeof (float128)); if (++next_arg.f128 == gpr_end.f128) -- cgit v1.2.1
