[Bug gas/29794] find_reloc_table_entry in tc-aarch64.c should be speed up
https://sourceware.org/bugzilla/show_bug.cgi?id=29794
--- Comment #2 from Andrew Pinski ---
There is another thing which could be done is do strchr up front to find the
other : and then match the length and not do the strncasecmp in that case.
That is:
static struct reloc_table_entry *
find_reloc_table_entry (char **str)
{
unsigned int i;
const char *relocnameinstrend = strchr(*str, ':');
if (!relocnameinstrend)
return NULL;
int reloclengthinstr = *str - relocnameinstrend;
for (i = 0; i < ARRAY_SIZE (reloc_table); i++)
{
int length = reloc_table[i].name_length;
if (length == -1)
length = strlen (reloc_table[i].name);
if (reloclengthinstr != length)
continue;
if (strncasecmp (reloc_table[i].name, *str, length) == 0
&& (*str)[length] == ':')
{
*str += (length + 1);
return _table[i];
}
}
return NULL;
}
- CUT
These two should give a reasonable speed up I think. Also reording the list to
the most used first will also speed it up (I think that is the reason why lo12
is first already).

[Bug gas/13509] branch target to the wrong location
http://sourceware.org/bugzilla/show_bug.cgi?id=13509 --- Comment #4 from Andrew Pinski pinskia at gcc dot gnu.org 2011-12-16 22:18:04 UTC --- The reason why GCC emits LABEL = . is because of the following reason: * Print debug labels as foo = . rather than foo: because they should represent a byte pointer rather than an ISA-encoded address. ... The .uleb128 requies $LFBxxx to match the FDE start address, which is likewise a byte pointer rather than an ISA-encoded address. So I think we should just delete the code in the assembler which moves the labels since they don't move = . based labels. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
