Summary:
Numerous test failures on hppa2.0w-hp-hpux11.00

Detailed description
I can build MPFR on this platform with the vendor compiler, but the test suite does not go well. This is for the current form of the 3.1 branch, obtained from svn://scm.gforge.inria.fr/svn/mpfr/branches/3.1 Here is what I get: [...] gmake check-TESTS gmake[2]: Entering directory `/home/cport/tmp/mpfr-3.1.1-dev/_build/tests' [tversion] GMP: header 5.0.5, library 5.0.5 [tversion] MPFR tuning parameters from default PASS: tversion PASS: tinternals PASS: tinits PASS: tisqrt PASS: tsgn PASS: tcheck PASS: tisnan PASS: texceptions PASS: tset_exp PASS: tset PASS: mpf_compat PASS: mpfr_compat PASS: reuse PASS: tabs PASS: tacos PASS: tacosh PASS: tadd PASS: tadd1sp Inexact flag error in mpfr_add_d (1) FAIL: tadd_d PASS: tadd_ui PASS: tagm PASS: tai PASS: tasin PASS: tasinh PASS: tatan PASS: tatanh PASS: taway PASS: tbuildopt PASS: tcan_round PASS: tcbrt Error in mpfr_cmp with x=7.38076162788329440000e-01, y=8.17863699638849640000e-01 mpfr_cmp(x,y)=0 FAIL: tcmp Error in mpfr_cmp2 for x=1.0e617 y=-1.0e-189 got 0 instead of 1 FAIL: tcmp2 Error in mpfr_cmp_d 2.345 and 2.0 FAIL: tcmp_d PASS: tcmp_ld PASS: tcmp_ui PASS: tcmpabs PASS: tcomparisons PASS: tconst_catalan PASS: tconst_euler PASS: tconst_log2 PASS: tconst_pi PASS: tcopysign PASS: tcos PASS: tcosh PASS: tcot PASS: tcoth PASS: tcsc PASS: tcsch Inexact flag error in mpfr_d_div FAIL: td_div Inexact flag error in mpfr_d_sub FAIL: td_sub PASS: tdigamma PASS: tdim PASS: tdiv Inexact flag error in mpfr_div_d FAIL: tdiv_d PASS: tdiv_ui That's all I've got, because at this point, the "teint" test spins (seemingly) forever. GMP 5.0.5 builds cleanly on this system, and its "make check" passes all tests.

Date: 2012-07-20 14:00 Sender: Vincent Lefèvre From debugging information (sent privately), there is at least a bug related to a double to unsigned long conversion on the platform (when the double is an integer representable in an unsigned long). Not a bug in MPFR. Closing.
Date: 2012-06-20 18:07 Sender: Daniel Richard G. I tried an MPFR build with GCC. It still links against a GMP built with the HP compiler, and thus doesn't use compiler flags beyond -g -O2. But all the tests pass. It appears that a compiler bug may be at fault. I just sent you e-mail.
Date: 2012-06-20 08:18 Sender: Paul Zimmermann the tset_d failure confirms the conversion from double to mpfr_t is wrong (the other way seems correct). I can help you to isolate the problem, but it will be easier by mail: please contact me at Paul dot Zimmermann at inria dot fr. By the way, did you try with GCC instead of the vendor compiler? We might also hit a bug of the vendor compiler. Paul Zimmermann
Date: 2012-06-20 04:18 Sender: Daniel Richard G. Here are the outputs from running those tests manually: host:/tmp/mpfr-3.1.1-dev/_build/tests$ ./tset_d ; echo $? Error in tset_d: expected 1.0, got 0.10E0 1 host:/tmp/mpfr-3.1.1-dev/_build/tests$ ./tget_d ; echo $? 0 The (gzipped) config.log file is attached.
Date: 2012-06-19 21:06 Sender: Paul Zimmermann Daniel, it seems all tests involving machine floating-point numbers fail. Maybe we wrongly recognize and convert to/from machine floating-point numbers. Please can you attach the config.log file, and run manually the tset_d and tget_d? Paul Zimmermann
