Upon further\ninvestigation, this definition appears to be a historical mistake.\n\nThis patch removes the MAX_FIXED_MODE_SIZE override, which fixes the error.\n\n\tPR target/120144\n\ngcc/ChangeLog:\n\t* config/mips/mips.h (MAX_FIXED_MODE_SIZE): Remove erroneous definition.\n\ngcc/testsuite/ChangeLog:\n\t* gcc.dg/torture/pr120144.c: New test.\n\nSigned-off-by: Carter Rennick<carter.rennick@gmail.com>\n---\n gcc/config/mips/mips.h | 4 ----\n gcc/testsuite/gcc.dg/torture/pr120144.c | 8 ++++++++\n 2 files changed, 8 insertions(+), 4 deletions(-)\n create mode 100644 gcc/testsuite/gcc.dg/torture/pr120144.c", "diff": "diff --git a/gcc/config/mips/mips.h b/gcc/config/mips/mips.h\nindex f52d0d2358c..c461d8aea3d 100644\n--- a/gcc/config/mips/mips.h\n+++ b/gcc/config/mips/mips.h\n@@ -1706,10 +1706,6 @@ FP_ASM_SPEC \"\\\n doesn't support 128-bit integers for MIPS32 currently. */\n #define LONG_LONG_ACCUM_TYPE_SIZE (TARGET_64BIT ? 128 : 64)\n \n-/* long double is not a fixed mode, but the idea is that, if we\n- support long double, we also want a 128-bit integer type. */\n-#define MAX_FIXED_MODE_SIZE MIPS_LONG_DOUBLE_TYPE_SIZE\n-\n /* Width in bits of a pointer. */\n #ifndef POINTER_SIZE\n #define POINTER_SIZE ((TARGET_LONG64 && TARGET_64BIT) ? 64 : 32)\ndiff --git a/gcc/testsuite/gcc.dg/torture/pr120144.c b/gcc/testsuite/gcc.dg/torture/pr120144.c\nnew file mode 100644\nindex 00000000000..e254771ea78\n--- /dev/null\n+++ b/gcc/testsuite/gcc.dg/torture/pr120144.c\n@@ -0,0 +1,8 @@\n+/* PR target/120144 */\n+/* { dg-do compile } */\n+/* { dg-require-effective-target int128 } */\n+\n+int f(unsigned __int128 t)\n+{\n+ return __builtin_clzg(t);\n+}\n", "prefixes": [ "v3" ] }
