* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-22611/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment. (libm-test-ulps.h): Don't refer to test_ulps in #include comment. (prev_max_error): New variable. (prev_real_max_error): Likewise. (prev_imag_max_error): Likewise.

(init_max_error): Take function name as argument. Look up ulps for that function. (print_ulps): Remove function. (print_max_error): Use prev_max_error instead of calling find_function_ulps. (print_complex_max_error): Use prev_real_max_error and prev_imag_max_error instead of calling find_complex_function_ulps. (check_float_internal): Take max_ulp parameter instead of calling find_test_ulps. Don't call print_ulps. (check_float): Update call to check_float_internal. (check_complex): Update calls to check_float_internal. (START): Pass argument to init_max_error. * math/gen-libm-test.pl (%results): Don't include "kind" information.

* s390: implement sotruss supportMike Frysinger2014-01-161-0/+62
| | | | | | | | | | | | | See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase. Note: while this works on s390x, the s390 code hangs when using -e. But it hangs regardless of this code (the hang seems to occur before the exit func is even called). I didn't look too closely at it as it seems to be an issue external to this file, so this code shouldn't make the situation any worse.

* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-232-0/+25
| | | | | | | | | | | | The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.

* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-292-4/+2
| | | | | | | | | Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.

* s390/s390x: Undef PSEUDO before redef.Carlos O'Donell2013-04-062-0/+2
| | | | | | | | | | | | | | | | | | | The s390 and s390x sysdep.h files include the more generic sysdep.h. The more generic sysdep.h defines PSEUDO. This causes an annoying CPP warning saying the PSEUDO was redefined. This patch removes the warning by undefining PSEUDO before the redefinition. This is in line with what all the other machines do. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> * sysdeps/s390/s390-32/sysdep.h: Undefine PSEUDO before redefinition. * sysdeps/s390/s390-64/sysdep.h: Likewise.
