Besides, it's silly. GCC however will generate a line number of
|
|
|
|
|
zero when it is pre-processing builtins for assembler-with-cpp files:
|
|
|
|
|
|
2012-03-13 17:59:57 +01:00
|
|
|
|
# 0 "<built-in>"
|
2005-08-07 12:34:52 +02:00
|
|
|
|
|
|
|
|
|
We do not want to barf on this, especially since such files are used
|
|
|
|
|
in the GCC and GDB testsuites. So we check for negative line numbers
|
|
|
|
|
rather than non-positive line numbers. */

Add .nop assembler directive
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions. SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated. If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.
For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction. The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit
is set to the maximum supported size.
2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte. A
target backend must override the default md_generate_nops to generate
proper no-op instructions. Otherwise, an error of unimplemented .nop

This has a split personality. We use expression() to read the
|
|
|
|
|
value. We can detect if the value won't fit in a byte or word.
|
|
|
|
|
But we can't detect if expression() discarded significant digits
|
|
|
|
|
in the case of a long. Not worth the crocks required to fix it. */

You can define TC_PARSE_CONS_EXPRESSION to do whatever you like
|
|
|
|
|
(for example, the HPPA does this). Otherwise, you can define
|
|
|
|
|
REPEAT_CONS_EXPRESSIONS to permit repeat counts. If none of these
|
|
|
|
|
are defined, which is the normal case, then only simple expressions
|
|
|
|
|
are permitted. */

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.

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.

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.

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.

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.

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.

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

for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.

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.

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.

by 0d 0f 0g or 0h. After observing the STRANGE way my BSD AS does its

rounded bits to the precision of the pseudo-op. Former AS did premature

truncation, restored noisy bits instead of trailing 0s AND gave you

Note - we are using the DWARF standard's definition of LEB128 encoding
|
|
|
|
|
where each 7-bit value is a stored in a byte, *not* an octet. This
|
|
|
|
|
means that on targets where a byte contains multiple octets there is
|
|
|
|
|
a *huge waste of space*. (This also means that we do not have to
|
|
|
|
|
have special versions of these functions for when OCTETS_PER_BYTE_POWER
|
|
|
|
|
is non-zero).
|
|
|
|
|
|
|
|
|
|
If the 7-bit values were to be packed into N-bit bytes (where N > 8)
|
|
|
|
|
we would then have to consider whether multiple, successive LEB128
|
|
|
|
|
values should be packed into the bytes without padding (bad idea) or
|
|
|
|
|
whether each LEB128 number is padded out to a whole number of bytes.
|
|
|
|
|
Plus you have to decide on the endianness of packing octets into a
|
|
|
|
|
byte. */

PR23040, .uleb128 directive doesn't accept some valid expressions
What a trip down a rabbit hole this bug has been.
First observation: You can't use deferred_expression in s_leb128.
deferred_expression implements the semantics of .eqv or '==', saving
an expression with minimal simplification for assignment to a symbol
so that the expression is evaluated at uses of the symbol. In
particular, the value of "dot" is not evaluated at the .eqv symbol
assignment, but later. When s_leb128 uses deferred_expression,
"later" is at the end of assembly, giving entirely the wrong value of
"dot". There is no way to fix this for the s_leb128 use without
breaking .equ (which incidentally was already somewhat broken, see
commit e4c2619ad1). So, don't use deferred_expression in s_leb128.
But that leads to the gas test elf/dwarf2-17 failing, because view
symbols are calculated with a chain of expression symbols. In the
dwarf2-17 .L1 case there is a "temp_sym_1 > temp_sym_2" expression,
with temp_sym_1 and temp_sym_2 on either side of a ".balign". Since
".balign" and many other directives moving "dot" are not calculated on
the first (and only) pass over source, .L1 cannot be calculated until
final addresses are assigned to frags. However, ".uleb128 .L1" *is*
calculated immediately, resulting in the wrong value.
The reason why .L1 is calculated immediately is that code in
expr.c:operand after the comment
/* If we have an absolute symbol or a reg, then we know its
value now. */
does as it says and fixes the value of .L1, because .L1 is assigned
to absolute_section in dwarf2dbg.c:set_or_check_view. So, correct
that to expr_section.
Unfortunately that fix leads to failure of the elf/dwarf2-5 test with
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L5'
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L11'
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L12'
So why is that? Well, it turns out that .L5 is defined in terms of
.L4, and apparently .L4 is undefined. But .L4 clearly is defined,
otherwise we would hit an error when trying to use .L4 a little
earlier. There are two copies of .L4! So, symbols are cloned when
that should not happen.
Symbol cloning is a technique used by gas to support saving the value
of symbols that change between uses, but that isn't the case with
.L4. Only one value is set and used for .L4, but indeed .L4 was being
cloned by symbol_clone_if_forward_ref. This despite no forward refs
being present. Also, .L4 is a local symbol and a cursory glance at
symbol_clone_if_forward_ref "if (symbolP && !LOCAL_SYMBOL_CHECK (symbolP))"
would seem to prevent cloning of local symbols. All is not as it
seems though, a curse of using macros. LOCAL_SYMBOL_CHECK modifies
its argument if a "struct local_symbol" is converted to the larger
"struct symbol", as happens when assigning a view symbol value.
That fact results in the recursive call to symbol_clone_if_forward_ref
returning a different address for "add_symbol". This problem could
have been fixed by using symbol_same_p rather than comparing symbol
pointers, but I thought it better to use the real symbol throughout.
Note that symbol_find_exact also returns the real symbol for a
converted local symbol.
Finally, this patch does expose lack of support for forward symbol
definitions in various targets. For example:
alpha-linux +ERROR: ../ld/testsuite/ld-elf/pr11138-2.c: compilation failed
This is caused by view symbol uses. On alpha-linux-gcc (GCC) 8.1.1
20180502 they happen to occur in .byte directives so were silently
broken in cases like elf/dwarf2-17 anyway.
/tmp/ccvtsMfU.s: Assembler messages:
/tmp/ccvtsMfU.s: Fatal error: unhandled relocation type BFD_RELOC_8
/tmp/ccvtsMfU.s: Fatal error: unhandled relocation type BFD_RELOC_8
md_apply_fix on those targets needs to handle fixups that resolve down
to a constant.
