* gas: equates of registersJan Beulich2023-05-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems: symbol_equated_p() doesn't recognize equates of registers, and S_CAN_BE_REDEFINED() goes by section rather than by expression type. Both together undermine .eqv and .equiv clearly meaning to guard the involved symbols against re-definition (both ways). To compensate pseudo_set() now using O_symbol and S_CAN_BE_REDEFINED() now checking for O_register, - for targets creating register symbols through symbol_{new,create}() -> symbol_init() -> S_SET_VALUE() (alpha, arc, dlx, ia64, m68k, mips, mmix, tic4x, tic54x, plus anything using cgen or itbl-ops), have symbol_init() set their expressions to O_register, - x86'es parse_register() also can't go by section anymore when trying to "look through" equates; probably symbol_equated_p() should have been used there from the beginning, if only that had worked for equates of registers, - various targets need to "look through" equates when parsing insn operands (which also helps transitive forward equates); perhaps even more ought to, but many don't look to consider the possibility of register equates in the first place. This was uncovered by code reported in PR gas/30274 (duplicating PR gas/30272), except that there .eqv was used when really .equ was meant. Therefore that bug report is addressed here only in so far as gas wouldn't crash anymore; the code there still won't assemble successfully, just that now the issues there are properly diagnosed.
* gas: apply md_register_arithmetic also to unary '+'Jan Beulich2023-03-171-1/+1
| | | | | | | | | | | | | | Even a unary '+' has to be considered arithmetic; at least on x86 in Intel Syntax mode otherwise bogus insn operands may be accepted. Convert this specific case to binary + (i.e. 0 + <register>). (An implication is that md_operator(,1,) would need to deal with arch- specific equivalents of unary '+' is a similar way, if such an arch- specific variant would be specified in the first place.) To avoid duplicating what make_expr_symbol() does to construct a constant-zero expression, simply make its previously local variable a file-scope static one. This way there's also no need to invoke clean_up_expression().

| | | | | | | | | | The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
* Power10 bignum operandsAlan Modra2021-04-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When built on a 32-bit host without --enable-64-bit-bfd, powerpc-linux and other 32-bit powerpc targeted binutils fail to assemble some power10 prefixed instructions with 34-bit fields. A typical error seen when running the testsuite is .../gas/testsuite/gas/ppc/prefix-pcrel.s:10: Error: bignum invalid In practice this doesn't matter for addresses: 32-bit programs don't need or use the top 2 bits of a d34 field when calculating addresses. However it may matter when loading or adding 64-bit constants with paddi. A power10 processor in 32-bit mode still has 64-bit wide GPRs. So this patch enables limited support for O_big PowerPC operands, and corrects sign extension of 32-bit constants using X_extrabit. * config/tc-ppc.c (insn_validate): Use uint64_t for operand values.

* GAS: Replace macro LITERAL_PREFIXDOLLAR_HEX with a runtime value.John Darrington2019-05-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | In an upcoming commit, I need to be able to set the prefix used to introduce hexadecimal literal constants using a command line flag. This is not currently possible, because the switch which determines this (LITERAL_PREFIXDOLLAR_HEX) is a macro set at build time. This change substitutes it for a variable to be set at start up. gas/ChangeLog: * expr.c (literal_prefix_dollar_hex): New variable. (operand)[case '$']: Use the new variable instead of the old macro. Also, move this instance of "case '$'" next to the other one, and enable it only in the complementary proprocessor case. * expr.h (literal_prefix_dollar_hex): Declare it. * config/tc-epiphany.c (md_begin): Assign literal_prefix_dollar_hex. * config/tc-ip2k.c: ditto * config/tc-mt.c: ditto * config/tc-epiphany.h (LITERAL_PREFIXDOLLAR_HEX): Remove macro definition. * config/tc-ip2k.h: ditto * config/tc-mt.h: ditto

* This adjusts equate handling byNick Clifton2005-10-111-2/+13
| | | | | | | | | | | | | | | - allowing true forward references (which will always assume the referenced symbols have at the point of use) through the new .eqv pseudo-op and the new == operator - disallowing changing .equiv-generated equates (so that the protection this provides is both forward and backward) - snapshotting equates when their value gets changed so that previous uses don't get affected by the new value. - allowing expressions in places where absolute expressions (or register names) are needed which were not completely resolvable at the point of their definition but which are fully resolvable at the point of use In addition it fixes PR/288.
