From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.c-torture/compile/pr39845.c | 45 +++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr39845.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr39845.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr39845.c b/gcc/testsuite/gcc.c-torture/compile/pr39845.c new file mode 100644 index 000000000..bd731989d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr39845.c @@ -0,0 +1,45 @@ + +/* { dg-options "-fno-short-enums" {target short_enums} } */ +typedef union tree_node *tree; +enum tree_code { EXCESS_PRECISION_EXPR }; +enum built_in_function { BUILT_IN_ACOS, BUILT_IN_FPCLASSIFY, BUILT_IN_ISFINITE }; +struct tree_base { + __extension__ enum tree_code code : 16; + unsigned side_effects_flag : 1; +}; +struct tree_exp { + tree operands[1]; +}; +struct tree_function_decl { + __extension__ enum built_in_function function_code : 11; + unsigned static_ctor_flag : 1; +}; +union tree_node { + struct tree_base base; + struct tree_function_decl function_decl; + struct tree_exp exp; +}; +static tree +convert_arguments (tree fundecl) +{ + tree val = (void *)0; + unsigned int parmnum; + unsigned char type_generic_remove_excess_precision = 0; + switch (((fundecl)->function_decl.function_code)) + { + case BUILT_IN_ISFINITE: + case BUILT_IN_FPCLASSIFY: + type_generic_remove_excess_precision = 1; + } + for (parmnum = 0;; ++parmnum) + if (((enum tree_code) (val)->base.code) == EXCESS_PRECISION_EXPR + && !type_generic_remove_excess_precision) + val = ((val)->exp.operands[0]); + return val; +} +tree +build_function_call_vec (tree function) +{ + return convert_arguments (function); +} + -- cgit v1.2.3
