From 99ef2719fb3d703fe38c4113cd7f5adec516dd3a Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Fri, 28 Oct 2016 20:29:21 +0200 Subject: test: remove test suite The test suite is now a developed in a separate git repository. See here: http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git The test suite should be just like every other software compiled with the cross-toolchain. In the past strange problems where found when the test suite got build in the toolchain creation step. --- test/mmap/mmap2.c | 46 ---------------------------------------------- 1 file changed, 46 deletions(-) delete mode 100644 test/mmap/mmap2.c (limited to 'test/mmap/mmap2.c') diff --git a/test/mmap/mmap2.c b/test/mmap/mmap2.c deleted file mode 100644 index 1d5f5db5e..000000000 --- a/test/mmap/mmap2.c +++ /dev/null @@ -1,46 +0,0 @@ -/* When trying to map /dev/mem with offset 0xFFFFF000 on the ARM platform, mmap - * returns -EOVERFLOW. - * - * Since off_t is defined as a long int and the sign bit is set in the address, - * the shift operation shifts in ones instead of zeroes - * from the left.
