Less severe error found during the parsing, very possibly because that

|
||
|

AARCH64_OPDE_SYNTAX_ERROR
|
||
General syntax error; it can be either a user error, or simply because

that GAS is trying a wrong instruction template.
|

AARCH64_OPDE_FATAL_SYNTAX_ERROR
|
||
Definitely a user syntax error.
|
||
|
||
AARCH64_OPDE_INVALID_VARIANT
|
||
No syntax error, but the operands are not a valid combination, e.g.
|
||
FMOV D0,S0
|
||
|
||
AARCH64_OPDE_UNTIED_OPERAND
|
||
The asm failed to use the same register for a destination operand
|
||
and a tied source operand.
|
||
|
||
AARCH64_OPDE_OUT_OF_RANGE
|
||
Error about some immediate value out of a valid range.
|
||
|
||
AARCH64_OPDE_UNALIGNED
|
||
Error about some immediate value not properly aligned (i.e. not being a
|
||
multiple times of a certain value).
|
||
|
||
AARCH64_OPDE_REG_LIST
|
||
Error about the register list operand having unexpected number of
|
||
registers.
|
||
|
||
AARCH64_OPDE_OTHER_ERROR
|
||
Error of the highest severity and used for any severe issue that does not
|
||
fall into any of the above categories.
|
||
|
||
The enumerators are only interesting to GAS. They are declared here (in
|
||
libopcodes) because that some errors are detected (and then notified to GAS)
|
||
by libopcodes (rather than by GAS solely).
|
||
|
||
The first three errors are only deteced by GAS while the
|
||
AARCH64_OPDE_INVALID_VARIANT error can only be spotted by libopcodes as
|
||
only libopcodes has the information about the valid variants of each
|
||
instruction.
|
||
|
||
The enumerators have an increasing severity. This is helpful when there are
|
||
multiple instruction templates available for a given mnemonic name (e.g.
|
||
FMOV); this mechanism will help choose the most suitable template from which
|
||
the generated diagnostics can most closely describe the issues, if any. */
