Dear all,
Currently Wextra warns about a pointer compared against integer zero
with <, <=, >, or >=. This warning is not available in C++ (the
documentation does not say this) and it is implemented in
gcc/c-typeck.c (build_binary_op) in this manner:
else if (code0 == POINTER_TYPE && null_po
Hi.
I seem unable to get a QImode shift instruction from this code:
unsigned char x;
void qishifttest2 (unsigned int c)
{
x <<= c;
}
Already at the first tree dump, there's a promotion to int:
;; Function qishifttest2 (qishifttest2)
;; enabled by -tree-original
{
x = (unsig

should have been generated. Also, notice the redundant zero extension.

Hello all,
I am building a GCC Compiler. I have some ifdef checks in the compiler
source code. In case i define a symbolic literal in command line while
compiling a sample program, I want that set of statements to be
invoked after ifdef checks.
e.g.
GCC Source:
#ifdef SHAFI_DEBUG
printf("\n Shaf
