* Fix ulps regeneration for *-finite tests.Joseph Myers2016-01-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On running tests after from-scratch ulps regeneration, I found that some libm tests failed with ulps in excess of those recorded in the from-scratch regeneration, which should never happen unless those ulps exceed the limit on ulps that can go in libm-test-ulps files. Failure: Test: atan2_upward (inf, -inf) Result: is: 2.35619498e+00 0x1.2d97ccp+1 should be: 2.35619450e+00 0x1.2d97c8p+1 difference: 4.76837159e-07 0x1.000000p-21 ulp : 2.0000 max.ulp : 1.0000 Maximal error of `atan2_upward' is : 2 ulp accepted: 1 ulp Failure: Test: carg_upward (-inf + inf i) Result: is: 2.35619498e+00 0x1.2d97ccp+1 should be: 2.35619450e+00 0x1.2d97c8p+1 difference: 4.76837159e-07 0x1.000000p-21 ulp : 2.0000 max.ulp : 1.0000 Maximal error of `carg_upward' is : 2 ulp accepted: 1 ulp The problem comes from the addition of tests for the finite-math-only versions of libm functions. Those tests share ulps with the default function variants. make regen-ulps runs the default tests before the finite-math-only tests, concatenating the resulting ulps before feeding them to gen-libm-test.pl to generate a new libm-test-ulps file. But gen-libm-test.pl always takes the last ulps value given for any (function, type) pair. So, if the largest ulps for a function come from non-finite inputs, a from-scratch regeneration loses those ulps. This patch fixes gen-libm-test.pl, in the case where there are multiple ulps values for a (function, type) pair - which can only happen as part of a regeneration - to take the largest ulps value rather than the last one. Tested for ARM / MIPS / powerpc-nofpu. * math/gen-libm-test.pl (parse_ulps): Do not reduce already-recorded ulps. * sysdeps/arm/libm-test-ulps: Regenerated. * sysdeps/mips/mips32/libm-test-ulps: Likewise. * sysdeps/mips/mips64/libm-test-ulps: Likewise. * sysdeps/powerpc/nofpu/libm-test-ulps: Likewise.

| | | | | | | | | | | This patch regenerates libm-test-ulps for ARM. As before it may be useful for someone building for a configuration with VFMA enabled to do a followup regeneration for any additional ulps in that configuration. Committed. * sysdeps/arm/libm-test-ulps: Regenerated.
* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-7716/+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.

* Move arm from ports to libc.Joseph Myers2014-02-081-0/+8028
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've moved the ARM port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/arm sysdeps/arm git mv ports/sysdeps/unix/arm sysdeps/unix/arm git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.arm similar to that at the top of ChangeLog.powerpc. There is deliberately no NEWS change, as I think it makes the most sense to put in a general note above all ports having moved if we can achieve that for 2.20. Tested that disassembly of installed shared libraries for arm is the same before and after this patch, except for data (not instructions) in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the path by which that file is found, and so by which it appears in the assertion message, changes as a result of the move). * sysdeps/arm: Move directory from ports/sysdeps/arm. * sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm. * sysdeps/unix/sysv/linux/arm: Move directory from ports/sysdeps/unix/sysv/linux/arm. * README: Update listing for arm-*-linux-gnueabi. ports/ChangeLog.arm: * sysdeps/arm: Move directory to ../sysdeps/arm. * sysdeps/unix/arm: Move directory to ../sysdeps.arm. * sysdeps/unix/sysv/linux/arm: Move directory to ../sysdeps/unix/sysv/linux/arm.
