Hi,
When analyzing code size differences between a 4.9.x compiler and
trunk for the AVR target, I found quite a few cases where extra
registers were being used to hold smaller types (two 8 bit registers
for a uint8_t, for example).
On deeper analysis, I found that the VRP pass (gcc/tree
Dear List,
I am currently trying to understand an issue to do with complex number
support in gcc.
Consider the following code:
#include
int main()
{
float _Complex a = _Complex_I;
}
Attempting to compile this with these commands is fine:
$ g++ tmp.cpp -std=gnu++11
$ g++ tmp.cpp
