2013-04-06New Makefile target `regen-ulps'.Carlos O'Donell3-19/+78
The wiki "Regeneration" page has this to say about update ULPs. "The libm-test-ulps files are semiautomatically updated. To update an ulps baseline, run each of the failing tests (test-float, test-double, etc.) with -u; this will generate a file called ULPs; concatenate each of those files with the existing libm-test-ulps file, after removing any entries for particularly huge numbers of ulps that you do not want to mark as expected. Then run gen-libm-test.pl -n -u FILE where FILE is the concatenated file produced in the previous step. This generates a file called NewUlps which is the new sorted version of libm-test-ulps." The same information is listed in math/README.libm-test, and is a lot of manual work that you often want to run over-and-over again while working on a particular test. The `regen-ulps' convenience target does this automatically for developers. We strictly assume the source tree is readonly and add a new --output-dir option to libm-test.inc to allow for writing out ULPs to $(objpfx). When run the new target does the following: * Starts with the baseline ULPs file. * Runs each of the libm math tests with -u. * Adds new changes seen with -u to the baseline. * Sorts and prepares the test output with gen-libm-test.pl. * Leaves math/NewUlps in your build tree to copy to your source tree, cleanup, and checkin. The math test documentation in math/README.libm-test is updated document the new Makefile target. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> * Makefile.in (regen-ulps): New target. * math/Makefile [ifneq (no,$(PERL)]: Declare regen-ulps with .PHONY. [ifneq (no,$(PERL)] (run-regen-ulps): New variable. [ifneq (no,$(PERL)] (regen-ulps): New target. [ifeq (no,$(PERL)] (regen-ulps): New target. * math/libm-test.inc (ulps_file_name): Define. (output_dir): New variable. (options): Add "output-dir" option. (parse_opt): Handle 'o' case. (main): If output_dir is non-NULL use it as a prefix otherwise use "". * math/README.libm-test: Update `How can I generate "libm-test-ulps"?'

2013-03-22BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella1-0/+3
The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
