Hi all,
I've been working on a plugin that processes some data. My plugin
grabs some data from the tree. I'm trying to understand a certain
"weird" behaviour I am seeing. And yeah, I'm new to the mailing list
and gcc's innards! Be forgiving! :) I appreciate the help!
When I add:
register
Hi,
In scan_one_insn, gcc checks whether an insn loads a parameter from
its stack slot, and then
record the fact by decrease the memory cost.
What I do not understand is the check condition like below checks the
REG_EQUIV note, rather than
checking memory access using stack pointer directly.

In GCC 3.4.6, in order to create a single executable called "gcc" that
takes C code and produces assembler, I needed to put this code into gcc.c:
#ifdef SINGLE_EXECUTABLE
{
int cnt = 0;
while (commands[i].argv[cnt] != NULL)
{
cnt++;
}

The revision history of the FSF version of GCC between the EGCS split
and the merge was retained on premerge-fsf-branch. That lets me see
that this change was committed by Richard Kenner on 1998-10-04.
Thanks Ian. I contacted Richard but unfortunately he had no
evidence of communicating with me

I've run into another issue supporting a 20-bit integer for which I'd
appreciate a hint. With this code:
typedef long int __attribute__((__a20__)) int20_t;
int20_t xi;
int20_t addit () { xi += 0x54321L; }
xi ends up in mode PSImode, which is a MODE_PARTIAL_INT with 20 bits of
precision and
