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.dg/dfp/pragma-float-const-decimal64-8.c | 174 +++++++++++++++++++++ 1 file changed, 174 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/dfp/pragma-float-const-decimal64-8.c (limited to 'gcc/testsuite/gcc.dg/dfp/pragma-float-const-decimal64-8.c') diff --git a/gcc/testsuite/gcc.dg/dfp/pragma-float-const-decimal64-8.c b/gcc/testsuite/gcc.dg/dfp/pragma-float-const-decimal64-8.c new file mode 100644 index 000000000..39d38c1d8 --- /dev/null +++ b/gcc/testsuite/gcc.dg/dfp/pragma-float-const-decimal64-8.c @@ -0,0 +1,174 @@ +/* { dg-do compile } */ +/* { dg-options "-Wall" } */ + +/* N1312 7.1.1: The FLOAT_CONST_DECIMAL64 pragma. + C99 6.4.4.2a (New). + + Pragma STDC FLOAT_CONST_DECIMAL64 "shall occur either outside external + declarations or preceding all explicit declarations and statements + inside a compound statement." */ + +#pragma STDC FLOAT_CONST_DECIMAL64 OFF + +#define MAX 200 + +#pragma STDC FLOAT_CONST_DECIMAL64 ON + +double a; + +#pragma STDC FLOAT_CONST_DECIMAL64 OFF + +struct S1 { +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + int i; + int j; +}; + +struct S2 { + int i; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + int j; +}; + +struct S3 { + int i; + int j; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ +}; + +enum E1 { +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-error "#pragma" } */ + one, + two +}; + +enum E2 { + red, +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-error "#pragma" } */ + blue +}; + +enum E3 { + cat, + dog +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-error "#pragma" } */ +}; + +double +#pragma STDC FLOAT_CONST_DECIMAL64 OFF /* { dg-error "#pragma" } */ +b; + +double +f1 (void) +{ +#pragma STDC FLOAT_CONST_DECIMAL64 ON + return a; +} + +double +f2 (void) +{ + double b; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + b = 0.5; + return a + b; +} + +#pragma STDC FLOAT_CONST_DECIMAL64 OFF + +double +f3 (void) +{ + typedef double b32; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + b32 b = 0.5; + return b; +} + +double +f4 (int i) +{ +top: +#pragma STDC FLOAT_CONST_DECIMAL64 OFF /* { dg-warning "invalid location" } */ + if (i == 0) + return a; + a *= 2.; + i = 0; + goto top; +} + +double +f5 (int i) +{ + a = a * i; +#pragma STDC FLOAT_CONST_DECIMAL64 OFF /* { dg-warning "invalid location" } */ + return a * 2.; +} + +double +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-error "#pragma" } */ +f6 (void) +{ + return a; +} + +double +f7 +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-error "#pragma" } */ +(void) /* { dg-error "before" } */ +{ + return a; +} + +double +f8 (void) +{ + { +#pragma STDC FLOAT_CONST_DECIMAL64 OFF + } +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + return a; +} + +extern void foo9 (void *); + +double +f9 (void) +{ + __label__ here; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + foo9 (&&here); +here: + return a; +} + +double +f10 (void) +{ + void foo10 (void) + { + a = 1.0; + } +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + return a; +} + +double +f11 (void) +{ + __extension__ + struct A { + struct { char a; }; + char b; + }; +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + return a; +} + +double +f12 (void) +{ + __extension__ ({ a = 0.5; }); +#pragma STDC FLOAT_CONST_DECIMAL64 ON /* { dg-warning "invalid location" } */ + return a; +} -- cgit v1.2.3
