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.dg/tree-ssa/cswtch.c | 81 ++++++++++++++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/cswtch.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/cswtch.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/cswtch.c b/gcc/testsuite/gcc.dg/tree-ssa/cswtch.c new file mode 100644 index 000000000..06710f217 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/cswtch.c @@ -0,0 +1,81 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-switchconv" } */ +/* { dg-do run } */ + +extern void abort (void); + +static int X, Y; + +int check(int param) +{ + int a = 0; + int b = 1; + + switch (param) + { + case -2: + a = 0; + b = -1; + break; + case 1: + case 2: + a = 8; + b = 6; + break; + case 3: + a = 9; + b = 5; + break; + case 6: + a = 10; + b = 4; + break; + default: + a = 16; + b = 1; + } + + X = a; + Y = b; + return 0; +} + +void assertions(int a, int b) +{ + if (X != a || Y != b) + abort(); + + return; +} + +int main () +{ + check (-10); + assertions (16, 1); + + check (-2); + assertions (0, -1); + + check(1); + assertions (8, 6); + + check(2); + assertions (8, 6); + + check(3); + assertions (9, 5); + + check(5); + assertions (16, 1); + + check(6); + assertions (10, 4); + + check(12); + assertions (16, 1); + + return 0; +} + +/* { dg-final { scan-tree-dump "Switch converted" "switchconv" } } */ +/* { dg-final { cleanup-tree-dump "switchconv" } } */ -- cgit v1.2.3
