names with 'L' and 'R' suffixes (e.g. %fr19L, %fr19R) which

|

%r28 - %r29 have %ret0 - %ret1 as synonyms
|
2005-04-12 10:39:34 +02:00

%fr4 - %fr7 have %farg0 - %farg3 as synonyms
|
1999-05-03 09:29:11 +02:00
|
|
|
|
%r30 has %sp as a synonym

%r27 has %dp as a synonym

%r2 has %rp as a synonym

gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables. That's OK, but not best
practice. tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.

the .comm pseudo-op has the following syntax:

a block of memory <length> bytes long. <length> must be an absolute

|
expression. <length> bytes will be allocated in the current space

|
and subspace.
|

|
Also note the label may not even be on the same line as the .comm.
|
|
|
|
|
|
|
|
|
|
This difference in syntax means the colon function will be called
|

on the symbol before we arrive in pa_comm. colon will set a number
|
|

|
of attributes of the symbol that need to be fixed here. In particular

the value, section pointer, fragment pointer, flags, etc. What

a pain.

|

"T" field selectors create DLT relative fixups for accessing

|

|
|
globals and statics in PIC code; each DLT relative fixup creates
|
|
|
|
|
an entry in the DLT table. The entries contain the address of

the final target (eg accessing "foo" would create a DLT entry
|
|
|
|
|
with the address of "foo").
|
|
|
|
|
|
|
|
|
|
Unfortunately, the HP linker doesn't take into account any addend
|
|
|
|
|
when generating the DLT; so accessing $LIT$+8 puts the address of
|
|
|
|
|
$LIT$ into the DLT rather than the address of $LIT$+8.
|
|
|
|
|
|
|
|
|
|
The end result is we can't perform relocation symbol reductions for
|
|
|
|
|
any fixup which creates entries in the DLT (eg they use "T" field
|
|
|
|
|
selectors).

|
2000-07-15 14:57:14 +02:00
|
|
|
|
|
|
|
|
|
If a symbol is reduced to a section symbol, the assembler will
|
|
|
|
|
adjust the addend unless the symbol happens to reside right at
|
|
|
|
|
the start of the section. Additionally, the linker has no choice
|
|
|
|
|
but to manipulate the addends when coalescing input sections for
|
|
|
|
|
"ld -r". Since an LR% field selector is defined to round the
|
|
|
|
|
addend, we can't change the addend without risking that a LR% and
|
|
|
|
|
it's corresponding (possible multiple) RR% field will no longer
|
|
|
|
|
sum to the right value.
|
|
|
|
|
|
|
|
|
|
eg. Suppose we have
|
|
|
|
|
. ldil LR%foo+0,%r21
|
|
|
|
|
. ldw RR%foo+0(%r21),%r26
|
2000-07-19 08:30:49 +02:00
|
|
|
|
. ldw RR%foo+4(%r21),%r25
|
|
|
|
|
|
|
|
|
|
If foo is at address 4092 (decimal) in section `sect', then after
|
|
|
|
|
reducing to the section symbol we get
|
|
|
|
|
. LR%sect+4092 == (L%sect)+0
|
|
|
|
|
. RR%sect+4092 == (R%sect)+4092
|
|
|
|
|
. RR%sect+4096 == (R%sect)-4096
|
|
|
|
|
and the last address loses because rounding the addend to 8k
|
2003-11-21 15:38:06 +01:00
|
|
|
|
multiples takes us up to 8192 with an offset of -4096.
|
2000-07-19 08:30:49 +02:00
|
|
|
|
|
|
|
|
|
In cases where the LR% expression is identical to the RR% one we
|
|
|
|
|
will never have a problem, but is so happens that gcc rounds
|
|
|
|
|
addends involved in LR% field selectors to work around a HP
|
|
|
|
|
linker bug. ie. We often have addresses like the last case
|
2000-07-15 14:57:14 +02:00
|
|
|
|
above where the LR% expression is offset from the RR% one. */
