/* Here is a table of C type sizes on hppa with various compiles
and options. I measured this on PA 9000/800 with HP-UX 11.11
and these compilers:
/usr/ccs/bin/cc HP92453-01 A.11.01.21
/opt/ansic/bin/cc HP92453-01 B.11.11.28706.GP
/opt/aCC/bin/aCC B3910B A.03.45
gcc gcc 3.3.2 native hppa2.0w-hp-hpux11.11
cc : 1 2 4 4 8 : 4 8 -- : 4 4
ansic +DA1.1 : 1 2 4 4 8 : 4 8 16 : 4 4
ansic +DA2.0 : 1 2 4 4 8 : 4 8 16 : 4 4
ansic +DA2.0W : 1 2 4 8 8 : 4 8 16 : 8 8
acc +DA1.1 : 1 2 4 4 8 : 4 8 16 : 4 4
acc +DA2.0 : 1 2 4 4 8 : 4 8 16 : 4 4
acc +DA2.0W : 1 2 4 8 8 : 4 8 16 : 8 8
gcc : 1 2 4 4 8 : 4 8 16 : 4 4
Each line is:
compiler and options
char, short, int, long, long long
float, double, long double
char *, void (*)()
So all these compilers use either ILP32 or LP64 model.
TODO: gcc has more options so it needs more investigation.
