GMP functions that take doubles choke on non-finite values, avoid that.
src/ChangeLog addition:
2015-05-10 Aidan Kehoe <kehoea@parhasard.net>
* floatfns.c (double_to_integer):
Rename this from float_to_int to fit our newer, bignum-compatible
terminology.
GMP can signal SIGFPE when asked to turn NaN or infinity into a
bignum, and we're not prepared to handle that signal if the OS float
library routines don't do that, so check for those values
explicitly.
* floatfns.c (ceiling_two_float):
* floatfns.c (ceiling_one_float):
* floatfns.c (floor_two_float):
* floatfns.c (floor_one_float):
* floatfns.c (round_two_float):
* floatfns.c (round_one_float):
* floatfns.c (truncate_two_float):
* floatfns.c (truncate_one_float):
Call double_to_integer() with its new name.
* number.c:
Don't use the {bignum,ratio,bigfloat}_set_double functions
directly here, with GMP they can choke when handed non-finite C
doubles, call Ftruncate() and the new float_to_bigfloat() from
floatfns.c. Maybe we should extend number-gmp.c with GMP-specific
implementations that check for non-finite values.
tests/ChangeLog addition:
2015-05-10 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Backslash a few parentheses in the first column for the sake of
fontification.
* automated/lisp-tests.el:
Check that the rounding functions signal Lisp errors correctly
when handed positive and negative infinity and NaN.

/* Hey Emacs, this is -*- C -*- code! */ /* Synched up with: Not synched with FSF. */ /* Think twice before editing this file. Generated automatically by configure. The file startup.el guesses at reasonable values for load-path, exec-path, and lock-directory. This means that if you move emacs and its associated sub-tree to a different place in the filesystem, or to a different machine, you won't have to do anything for it to work. If you define the paths in this file then they will take precedence over any value generated by the heuristic in startup.el. The hardcoded paths will be checked to see if they are valid, in which case they will be used. Otherwise the editor will attempt to make its normal guess. See the NEWS file for a description of the heuristic used to locate the lisp and exec directories at startup time. If you are looking at this file because you are having trouble, then you would be much better off arranging for those heuristics to succeed than defining the paths in this file. ** Let me say that again. If you're editing this file, you're making ** a mistake. Re-read the section on installation in ../etc/NEWS. If it defines anything, this file should define some subset of the following: PATH_PROGNAME The name of the Emacs variant that's running. PATH_VERSION The version id of the Emacs variant that's running. PATH_EXEC_PREFIX The value of --exec-prefix. PATH_PREFIX The value of --prefix. PATH_LOADSEARCH The default value of `load-path'. PATH_MODULESEARCH The default value of `module-load-path'. PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-early-packages'. PATH_LATE_PACKAGE_DIRECTORIES The value of `--with-late-packages'. PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-last-packages'. PATH_PACKAGEPATH The default value of `package-path'. PATH_SITE The default location of site-specific Lisp files. PATH_SITE_MODULES The default location of site-specific modules. PATH_EXEC The default value of `exec-directory' and `exec-path'. (exec-path also contains the value of whatever is in the PATH environment variable.) PATH_DATA The default value of `data-directory'. This is where architecture-independent files are searched for. PATH_INFO This is where the info documentation is installed. PATH_INFOPATH The default value of `Info-directory-list'. These are additional places info files are searched for. */ #define PATH_PROGNAME "@PROGNAME@" #define PATH_VERSION "@version@" #ifdef EXEC_PREFIX_USER_DEFINED #define PATH_EXEC_PREFIX "@EXEC_PREFIX@" #endif #ifdef PREFIX_USER_DEFINED #define PATH_PREFIX "@PREFIX@" #endif #ifdef LISPDIR_USER_DEFINED #define PATH_LOADSEARCH "@LISPDIR@" #endif #ifdef MODULEDIR_USER_DEFINED #define PATH_MODULESEARCH "@MODULEDIR@" #endif #ifdef SITELISPDIR_USER_DEFINED #define PATH_SITE "@SITELISPDIR@" #endif #ifdef SITEMODULEDIR_USER_DEFINED #define PATH_SITE_MODULES "@SITEMODULEDIR@" #endif #ifdef EARLY_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_EARLY_PACKAGE_DIRECTORIES "@EARLY_PACKAGE_DIRECTORIES@" #endif #ifdef LATE_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_LATE_PACKAGE_DIRECTORIES "@LATE_PACKAGE_DIRECTORIES@" #endif #ifdef LAST_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_LAST_PACKAGE_DIRECTORIES "@LAST_PACKAGE_DIRECTORIES@" #endif #ifdef PACKAGE_PATH_USER_DEFINED #define PATH_PACKAGEPATH "@PACKAGE_PATH@" #endif #ifdef ARCHLIBDIR_USER_DEFINED #define PATH_EXEC "@ARCHLIBDIR@" #endif #ifdef ETCDIR_USER_DEFINED #define PATH_DATA "@ETCDIR@" #endif #ifdef DOCDIR_USER_DEFINED #define PATH_DOC "@DOCDIR@" #endif #ifdef INFODIR_USER_DEFINED #define PATH_INFO "@INFODIR@" #endif #ifdef INFOPATH_USER_DEFINED #define PATH_INFOPATH "@INFOPATH@" #endif
