* [svn-r12440] Purpose:Quincey Koziol2006-06-271-24/+24
| | | | | | | | | | | Code cleanup Description: Trim trailing whitespace in Makefile.am and C/C++ source files to make diffing changes easier. Platforms tested: None necessary, whitespace only change
* [svn-r12435] Purpose: Bug fixRaymond Lu2006-06-231-3/+15
| | | | | | | | | | | | Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned) long long to long double. When the bit sequences are 0x003ff..., 0x007fff..., 0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big as they should be. Solution: Detect the error in configure and disable the compiler conversion and test case. Platforms tested: h5committest, Mac OS 10.4, and fuss.
* [svn-r12425] Purpose: Bug fixRaymond Lu2006-06-201-3/+19
| | | | | | | | | | | | | | | Description: Data conversion from long double to (unsigned) long long returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The conversions start to go wrong when the long double is 20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the converted values go wild. Solution: Detect this error in configure.in and disable compiler conversions from long double to (unsigned) long long for Mac OS 10.4 and IRIX64 6.5. Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.

There're some details not yet included, 1. the alignment detection for VAX order in H5detect.c. 2. support for special values in library conversion functions. 3. the infinity for VAX in H5T_init_inf. 4. support for VAX types in printing hexadecimal format. Platforms tested: h5committest and fuss.
* [svn-r11886] Purpose:Quincey Koziol2006-01-231-9/+11
| | | | | | | | | | | | | Code cleanup Description: Check in some of the code cleanups from working on the external link support. (This doesn't include any of the external link features) Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX.4 (amazon) Linux 2.4
* [svn-r11771] Purpose:Quincey Koziol2005-12-081-2/+1
| | | | | | | | | | | | Code cleanup Description: Fix a bunch of warnings flagged by Windows compilers. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11415] Purpose: Internal design change.Raymond Lu2005-09-141-1/+1
| | | | | | | | | | | | | | | | | Description: H5T_register() replaces any existing data conversion path with a new path. Solution: Added a parameter to H5T_register() and H5T_path_find() to signal the library whether the new conversion path is from API function H5Tregister() or from private function like H5T_init_interface(). If it is from H5Tregister(), replace existing path. If it's from H5T_init_interface() and the library is trying to register default hard conversion functions, don't replace existing path because the path is registered by the library. For example, the library registered H5T_conv_int_float() and is trying to register H5T_conv_long_float(). The size of long is equal to int. There's no need to replace the path H5T_conv_int_float(). Platforms tested: h5committest and fuss.
* [svn-r11414] Purpose: Rename a API functionRaymond Lu2005-09-141-6/+6
| | | | | | | | | | | Description: The API function H5Tis_hard() which was recently checked in has been renamed to H5Tcompiler_conv() to be more descriptive. No other changes. Platforms tested: fuss - simple change. Misc. update: config/lt_vers.am to update libtool version.

* [svn-r11395] Purpose: Bug fixRaymond Lu2005-09-121-0/+226
| | | | | | | | | | | | | | | | | | Description: Quincey added the condition branch (else if (*((ST*)S) != (ST)((DT)(*((ST*)S))))) in the definition of the macro H5T_CONV_Fx_CORE. It handles a special situation when the source is "float" and assigned the value of "INT_MAX". Compilers do roundup making this value "INT_MAX+1". This branch is to check that situation and return exception for some compilers, mainly GCC. The branch if (*((ST*)S) > (DT)(D_MAX) || (S_PREC < D_PREC && *((ST*)S) == (DT)(D_MAX))) is for some compilers like Sun, HP, IBM, and SGI where under the same situation the "int" doesn't overflow. A test was added to dt_arith.c to check 2 conversions, from float to int where the float is INT_MAX, and from double to signed char where the double is SCHAR_MAX. Platforms tested: h5committest and fuss.
* [svn-r11355] Purpose: A new API function and its test.Raymond Lu2005-09-061-0/+63
| | | | | | | | | Description: Put in a new API funciton, H5Tis_hard. It checks whether the conversion function from a native type to another native type is a compiler (hard) conversion. Also checked a test in test/dt_arith.c. Platforms tested: h5committest and fuss.
* [svn-r11345] Purpose:Quincey Koziol2005-09-031-1/+1
| | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Address most of datatype conversion exception handling bug that Ed Hartnett reported. (He's reported a different problem now, but we're closer at least). Also, condense exception handling #ifdef's into one location instead of spread out in so many places. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11311] Purpose: New features.Raymond Lu2005-08-291-43/+43
| | | | | | | | | | | | | | | | | | | | Description: Added 2 new configure options, --enable-exception and --enable-accuracy. --enable-exception lets the library check whether user's exception handling functions are present during compiler data conversions and use them if they are. When it's disabled, this step is skipped to improve conversion speed. This step isn't implemented yet for soft conversions because there would be little gain in speed. --enable-accuracy guarantees data accuracy during data conversions. It means the library will choose compiler conversions only if the accurate data is secured. Otherwise, the library will go for the library's own conversions. If this option is disabled, the library uses compiler conversions in favor of their speed as long as they work even if data can be incorrect. Platforms tested: h5committest and fuss. Some systems may fail after this checkin.
* [svn-r11248] Purpose:Quincey Koziol2005-08-151-1/+1
| | | | | | | | | | Code cleanup Description: Fix minor difference in datatype conversion exception callback routine. Platforms tested: FreeBSD 4.11 (sleipnir) w/C++
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-202/+202
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11144] Purpose:Quincey Koziol2005-07-231-22/+104
| | | | | | | | | | | New port Description: Elena asked me to check in her NEC SX-6 work, so here it is! :-) Platforms tested: FreeBSD 4.11 (sleipnir) NEC SX-6 (by Elena)
* [svn-r11087] Purpose: Bug fix.Raymond Lu2005-07-191-90/+109
| | | | | | | | | | | | | | Description: When converting floating-point numbers to integers and the values of floating-point number are greater than the maximal value of integer, Cray X1 generates floating exception. Solution: Added a test in configure to detect Cray X1's exception. Set a flag to indicate the machine that can handle overflow converting all floating-point to all integer types. This flag should be set for all machines, except for Cray X1 where floating exception is generated when the floating-point value is greater than the maximal integer value. Platforms tested: Cray X1 and h5committest.
* [svn-r10962] Purpose: Solve the Difference of Compiler and LibraryRaymond Lu2005-06-201-2/+56
| | | | | | | | | | | | Description: In this data conversion test, from floating number to floating number, when the source is bigger than the destination, overflow may happen. The library assign INFINITY while compiler's behavior is undefined. A compiler like SGI assigns the maximal value for the destination. Solution: When this situation occurs, simply check if the destination is INFINITY instead of comparing values. Platforms tested: modi4 and h5committest.
* [svn-r10931] Purpose: Adjust Test Program and RenameRaymond Lu2005-06-171-0/+4672
Description: Renamed test/dt_atomic.c to test/dt_arith.c(an abbreviation of "arithmetic data types") to better describe the program. This checkin broke down into three sections when the floating-point numbers are the source, normalized, denormalized, and special values. If there's any difference of destination values, only normalized value test reports failure. The other 2 report only as warning. Platforms tested: h5commitest and fuss Misc. update: MANIFEST
