This is speed comparison of GCC 8 builds compared to my system GCC 7.3.0

I run empty C and C++ source file, tramp3d and the rest are some big beasts

Hi all,
The problem described here probably only affects targets whose ABI allow to
pass structured
arguments of certain size via registers.
If the mode of the parameter type is BLKmode, in the callee, during RTL
expanding,
a stack slot will be reserved for this parameter, and the incoming val

Hi,
Thank you Richard and Honza for the suggestions. If I understand correctly,
the issue is that LTO file format keeps changing per compiler versions, so
we need a more “stable” representation and the first step for that would be
to “stabilize” representations for lto-cgraph and symbol table ? Co
Hi,
For the following test-case,
int a;
__attribute__((noinline))
static void foo()
{
a = 3;
}
int main()
{
a = 4;
foo ();
return a;
}
I assume it's safe to remove "a = 4" since 'a' would be overwritten
by call to foo ?
IIUC, ipa-reference pass does mod/ref analysis to compute side-eff

Hello.
Many significant changes has landed in mainline and will be released as GCC 8.1.
I decided to use various GCC configs we have and test how there configuration
differ
in size and also binary size.
This is first part where I measured binary size, speed comparison will follow.
Configuration
