Hi,
In one of my project, I noticed that the compilation time for a code
using gcc/4.0.2 increased from 10 sec to 24 sec. I could not figure out
the reason for this marked increase in the compilation time.
For this project, the compilation time is very crucial and hence
I would really appreciate any useful suggestions.
==============================================
code1.cc
// This takes only 10 sec for compilation
void func(sim_t sim, int pc)
{
{
count++; // Line 1
sim->_sym30679_5(7, 0, 100); // Line 2
}
// Repeats like above piece of code 1000 times
// ...
//...
//...
}
=============================================
code2.cc:
// This takes 24 sec to do the compilation
// Line 1 is replaced by a another expression
void func(sim_t sim, int pc)
{
{
sim->NIA_write(sim->CIA_read() + 4);
sim->_sym30679_5(7, 0, 100); // Line 2
}
// Repeats like above piece of code 1000 times
// ...
//...
//...
}
==============================================
void NIA_write_internal(const bits<32> &x) {
NIA().set_data() = x;
};
void NIA_write(const bits<32> &x) {
NIA_write_internal(x);
NIA_trace();
};
bits<32> & CIA_read() {
return CIA().get_data();
};
==================================================
