I am working on GCC for a target architecture where clz(0) is defined and
is 32 (TriCore).
The code under test is the following:
#include
int f(unsigned int a) {
unsigned int res = 32 - __builtin_clz(a);
if(res > 0) printf("test");
return res;
}

Hello,
for a custom architecture I am working on, I would like to entirely disable
the usage of hardware floating point instructions in favor of library
methods on demand.
I need advice on what is the best strategy to do this. My idea is to:
- create a new flag (let's say -m[no-]float-insn or
Best regards

Good evening,
I need help understanding where some RTX comes from.
In my target.md I have the following expansion:
(define_expand "smaxsf3"
[(parallel [(set (match_dup 3)
(unspec:SI [(match_operand:SF 1 "register_operand" "")
(match_operand:SF
I am trying to understand how 'flag_pic' works.
It is used extensively in TARGET_OPTION_OVERRIDE functions in the form 'if
(flag_pic) ... '.
The flags fPic and fpic have a default value of -1, so as far as I
understand, if the two flags are not set in the command line, all 'if
(flag_pic)' will be t
