ragge 8cf98df79f Fixes for vax 4K pages. (Whereever did these go???) 1999-03-13 22:20:49 +00:00
matthias 00cd9c886f First batch of changes needed to make gas.new work with PIC on the ns32k.
Todo: Modify tc_gen_reloc to frob the relocations correctly, add code for
missing relocation types to libbfd.
1999-03-13 15:18:49 +00:00
mrg a3032595bd add LINK_SPEC defines that i have "-m elf{32,64}_sparc" set correctly, like other ports. 1999-03-11 00:11:10 +00:00
mycroft c0832bbcc0 Fix Yet Another Bug in fold_truthop(), which causes the RHS mask to be
truncated if lnbitsize<rnbitsize.
1999-03-10 12:25:40 +00:00
ross 059f13e362 The .IP tag must be one word. 1999-03-09 02:52:05 +00:00
jonathan 6217914988 Update declaratino of mips single_step() so it compiles again. 1999-03-08 02:09:51 +00:00
mycroft 1f559e1bda Change the section alignment to 2^20 to match the ldscript and old binutils.
XXX Should we change this?
1999-03-06 06:04:21 +00:00
mycroft 3171ae377b Fix another bug in fold_truthop(). When comparing two bitfields where the
lhs and rhs have the same size, but are in different bit positions, and the
masks are also shifted, we could erroneously omit the shift.
1999-03-04 10:08:08 +00:00
mycroft 391c435609 When folding two bitfield comparisons, make sure we include any mask applied
to the bitfields.  Fixes PR 7066.
1999-03-04 05:38:06 +00:00
matthias 5748a83696 Add invalid_float (from opcodes/ns32k-dis.c). 1999-03-02 07:59:33 +00:00
matthias 943fbfc027 about everything in these files got doubled during the 4.17 update. 1999-03-01 13:15:06 +00:00
ross 877897554f Make this build on alpha. Still doesn't work well, though, and now
it can't read corefiles.
1999-03-01 07:58:56 +00:00
jonathan 1192ce7d8f Patch FUNCTION_PROFILER to avoid code-scheduling botch when compiling
with -mabicalls: the gcc/egcs code emits hand-scheduled code with an
insn in a "jal _mcount" delayslot. But with -mabicalls, the "jal"
expands into a call via $t9 and the delay-slot is already filled.

See PR#5248.

tv bc2ff89d6b Suppress "symbol type changed" harmless warnings, which plague MIPS ELF32.
Patch from Jonathan Stone.
1999-02-06 04:15:49 +00:00
tv f87e85338c Revert another bogosity introduced in 2.9.1. ELF_LITERAL relocs, such as
those emitted for references to __sF, cannot have addends, so we *must*
have an extra lda rN,addend(rN) insn after the reloc to offset into the
memory area.  Don't try to make `all' cases use addends.

1999-02-05 13:29:51 +00:00
tv 82c5de77a5 Remove duplicate TYPE_OPERAND_FORMAT define, so that it uses the `#'
instead of `%' character.  Also remove the LINK_SPEC - no other NetBSD
platform sends `-X' to the linker by default, so make it uniform.

  quite old and out of maintenance)

kristerw ab2e248758 NetBSD always saves a_midmag as big-endian, but libbfd use the same
endianess as the arch in its internal structures, so we may have to change
the byte order when we write the exec header. The problem is that we need
the little endian version for libbfd to DTRT with the rest of the file.

Solve this by writing the exec header after the rest of the file has been
written.

mrg eb11f92a79 make this work. seems it needed `long int' and `long unsigned int' *exactly*
otherwise it wanted to dump core.  strange.  seems to work OK now.

mycroft facb3de742 Post-1.1.1pre2 patch from Jeff Law, via the egcs repository, which fixes some
problems with register allocation.
In particular, this should fix if_we on the i386, and GNU malloc on the m68k.

jonathan fe7810c7dc egcs-1.1 netbsd/mips config fixes:
1. Change linkspec to not pass -nostdlib to binutils ld, since on mips,
      ld parses "-nostdlib" as a set of short options which produce
      nonworking binaries.
  2.  Turn off ASM_OUTPUT_DEF definition: the egcs iris6.h says that
      our old definition (from gcc 2.7.2.2 iris5.h isnt really whats
      wanted here.
  3.  Turn off SET_ASM_OP (which defaults to .set) to stop
      dwarf2out.c from emitting debug(?) info for C++ using ".set",
      since both gas and mips as use .set to control assembler
      optimizations, not for equating labels. From iris6.h.
      and nonzero -G values are incompatible with PIC.
  4.  Set default GVALUE (for -G) to 0; this target always produces PIC
      by default, and on mips, PIC is incompatible with `small' segment.
  5.  Set TARGET_DEFAULT to enable "-mdebuga" to defeat
      GO_IF_LEGITIMATE_ADDRESS "smarts". GO_IF_LEGITIMATE_ADDRESS pretends
      that mips supports an address mode of constant + register.
      For constants larger than 16 bits, that relies on assembler fixups
      via $at.  egcs 1.1 (expr.c delta 1.76) may break up those addresses
      such that the backend cannot output them as offsets in load or store
      instructions anymore; no other patterns match so egcs coredumps.
