Yay, and of course this is not enough, as required alignment for 64bit
datatypes is of course different. We should shoot the one that came up
with
template <class T>
struct OffsetData
{
void reverseBytes();
int nodedata[6*Dim]; // domain data (same format as .layout)
bool isCompressed; // Is the data compressed
Offset_t offset; // offset in sizeof(T) units
T compressedValue; // Data value, if compressed
};
as possibly "portable" structure to write byte-for-byte to a file.
Placing bool between int and long long is surely not a good idea.
Changing the above to
int nodedata[6*Dim]; // domain data (same format as .layout)
union {
bool isCompressed; // Is the data compressed
char pad[8];
} u;
Offset_t offset; // offset in sizeof(T) units
_seems_ to "fix" the problem.
So, is the following patch ok? Tested on ia32, amd64 and ia64 linux.
2004Sep01 Richard Guenther <richard.guenther at uni-tuebingen.de>
* configure: add POOMA_HAS_LONG_LONG and POOMA_INT64
defines.
scripts/configure.ac: check for long long and sizes of
long and long long. Set POOMA_HAS_LONG_LONG and
POOMA_INT64 appropriately.
scripts/configure: regenerate.
src/IO/FileSetReader.h: use POOMA_INT64 for Offset_t,
pad bool inside OffsetData to 64bit using a union.
src/IO/FileSetWriter.h: likewise.
src/IO/FileSetReader.cpp: honour union.
