| 3 | Changes in 2.11:
|
|---|
| 4 |
|
|---|
| 5 | x86 gas now supports the full Pentium4 instruction set.
|
|---|
| 6 |
|
|---|
| 7 | Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
|
|---|
| 8 |
|
|---|
| 9 | Support for Motorola 68HC11 and 68HC12.
|
|---|
| 10 |
|
|---|
| 11 | Support for Texas Instruments TMS320C54x (tic54x).
|
|---|
| 12 |
|
|---|
| 13 | Support for IA-64.
|
|---|
| 14 |
|
|---|
| 15 | Support for i860, by Jason Eckhardt.
|
|---|
| 16 |
|
|---|
| 17 | Support for CRIS (Axis Communications ETRAX series).
|
|---|
| 18 |
|
|---|
| 19 | x86 gas has a new .arch pseudo op to specify the target CPU architecture.
|
|---|
| 20 |
|
|---|
| 21 | x86 gas -q command line option quietens warnings about register size changes
|
|---|
| 22 | due to suffix, indirect jmp/call without `*', stand-alone prefixes, and
|
|---|
| 23 | translating various deprecated floating point instructions.
|
|---|
| 24 |
|
|---|
| 25 | Changes in 2.10:
|
|---|
| 26 |
|
|---|
| 27 | Support for the ARM msr instruction was changed to only allow an immediate
|
|---|
| 28 | operand when altering the flags field.
|
|---|
| 29 |
|
|---|
| 30 | Support for ATMEL AVR.
|
|---|
| 31 |
|
|---|
| 32 | Support for IBM 370 ELF. Somewhat experimental.
|
|---|
| 33 |
|
|---|
| 34 | Support for numbers with suffixes.
|
|---|
| 35 |
|
|---|
| 36 | Added support for breaking to the end of repeat loops.
|
|---|
| 37 |
|
|---|
| 38 | Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL).
|
|---|
| 39 |
|
|---|
| 40 | New .elseif pseudo-op added.
|
|---|
| 41 |
|
|---|
| 42 | New --fatal-warnings option.
|
|---|
| 43 |
|
|---|
| 44 | picoJava architecture support added.
|
|---|
| 45 |
|
|---|
| 46 | Motorola MCore 210 processor support added.
|
|---|
| 47 |
|
|---|
| 48 | A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
|
|---|
| 49 | assembly programs with intel syntax.
|
|---|
| 50 |
|
|---|
| 51 | New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
|
|---|
| 52 |
|
|---|
| 53 | Added -gdwarf2 option to generate DWARF 2 debugging information.
|
|---|
| 54 |
|
|---|
| 55 | Full 16-bit mode support for i386.
|
|---|
| 56 |
|
|---|
| 57 | Greatly improved instruction operand checking for i386. This change will
|
|---|
| 58 | produce errors or warnings on incorrect assembly code that previous versions of
|
|---|
| 59 | gas accepted. If you get unexpected messages from code that worked with older
|
|---|
| 60 | versions of gas, please double check the code before reporting a bug.
|
|---|
| 61 |
|
|---|
| 62 | Weak symbol support added for COFF targets.
|
|---|
| 63 |
|
|---|
| 64 | Mitsubishi D30V support added.
|
|---|
| 65 |
|
|---|
| 66 | Texas Instruments c80 (tms320c80) support added.
|
|---|
| 67 |
|
|---|
| 68 | i960 ELF support added.
|
|---|
| 69 |
|
|---|
| 70 | ARM ELF support added.
|
|---|
| 71 |
|
|---|
| 72 | Changes in 2.9:
|
|---|
| 73 |
|
|---|
| 74 | Texas Instruments c30 (tms320c30) support added.
|
|---|
| 75 |
|
|---|
| 76 | The assembler now optimizes the exception frame information generated by egcs
|
|---|
| 77 | and gcc 2.8. The new --traditional-format option disables this optimization.
|
|---|
| 78 |
|
|---|
| 79 | Added --gstabs option to generate stabs debugging information.
|
|---|
| 80 |
|
|---|
| 81 | The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
|
|---|
| 82 | listing.
|
|---|
| 83 |
|
|---|
| 84 | Added -MD option to print dependencies.
|
|---|
| 85 |
|
|---|
| 86 | Changes in 2.8:
|
|---|
| 87 |
|
|---|
| 88 | BeOS support added.
|
|---|
| 89 |
|
|---|
| 90 | MIPS16 support added.
|
|---|
| 91 |
|
|---|
| 92 | Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
|
|---|
| 93 |
|
|---|
| 94 | Alpha/VMS support added.
|
|---|
| 95 |
|
|---|
| 96 | m68k options --base-size-default-16, --base-size-default-32,
|
|---|
| 97 | --disp-size-default-16, and --disp-size-default-32 added.
|
|---|
| 98 |
|
|---|
| 99 | The alignment directives now take an optional third argument, which is the
|
|---|
| 100 | maximum number of bytes to skip. If doing the alignment would require skipping
|
|---|
| 101 | more than the given number of bytes, the alignment is not done at all.
|
|---|
| 102 |
|
|---|
| 103 | The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
|
|---|
| 104 |
|
|---|
| 105 | The -a option takes a new suboption, c (e.g., -alc), to skip false conditionals
|
|---|
| 106 | in listings.
|
|---|
| 107 |
|
|---|
| 108 | Added new pseudo-op, .equiv; it's like .equ, except that it is an error if the
|
|---|
| 109 | symbol is already defined.
|
|---|
| 110 |
|
|---|
| 111 | Changes in 2.7:
|
|---|
| 112 |
|
|---|
| 113 | The PowerPC assembler now allows the use of symbolic register names (r0, etc.)
|
|---|
| 114 | if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) can be
|
|---|
| 115 | used any time. PowerPC 860 move to/from SPR instructions have been added.
|
|---|
| 116 |
|
|---|
| 117 | Alpha Linux (ELF) support added.
|
|---|
| 118 |
|
|---|
| 119 | PowerPC ELF support added.
|
|---|
| 120 |
|
|---|
| 121 | m68k Linux (ELF) support added.
|
|---|
| 122 |
|
|---|
| 123 | i960 Hx/Jx support added.
|
|---|
| 124 |
|
|---|
| 125 | i386/PowerPC gnu-win32 support added.
|
|---|
| 126 |
|
|---|
| 127 | SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the
|
|---|
| 128 | default is to build COFF-only support. To get a set of tools that generate ELF
|
|---|
| 129 | (they'll understand both COFF and ELF), you must configure with
|
|---|
| 130 | target=i386-unknown-sco3.2v5elf.
|
|---|
| 131 |
|
|---|
| 132 | m88k-motorola-sysv3* support added.
|
|---|
| 133 |
|
|---|
| 134 | Changes in 2.6:
|
|---|
| 135 |
|
|---|
| 136 | Gas now directly supports macros, without requiring GASP.
|
|---|
| 137 |
|
|---|
| 138 | Gas now has an MRI assembler compatibility mode. Use -M or --mri to select MRI
|
|---|
| 139 | mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the ``.mri
|
|---|
| 140 | 0'' is seen; this can be convenient for inline assembler code.
|
|---|
| 141 |
|
|---|
| 142 | Added --defsym SYM=VALUE option.
|
|---|
| 143 |
|
|---|
| 144 | Added -mips4 support to MIPS assembler.
|
|---|
| 145 |
|
|---|
| 146 | Added PIC support to Solaris and SPARC SunOS 4 assembler.
|
|---|
| 147 |
|
|---|
| 148 | Changes in 2.4:
|
|---|
| 149 |
|
|---|
| 150 | Converted this directory to use an autoconf-generated configure script.
|
|---|
| 151 |
|
|---|
| 152 | ARM support, from Richard Earnshaw.
|
|---|
| 153 |
|
|---|
| 154 | Updated VMS support, from Pat Rankin, including considerably improved debugging
|
|---|
| 155 | support.
|
|---|
| 156 |
|
|---|
| 157 | Support for the control registers in the 68060.
|
|---|
| 158 |
|
|---|
| 159 | Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
|
|---|
| 160 | provide for possible future gcc changes, for targets where gas provides some
|
|---|
| 161 | features not available in the native assembler. If the native assembler is
|
|---|
| 162 | used, it should become obvious pretty quickly what the problem is.
|
|---|
| 163 |
|
|---|
| 164 | Usage message is available with "--help".
|
|---|
| 165 |
|
|---|
| 166 | The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3
|
|---|
| 167 | also, but didn't get into the NEWS file.)
|
|---|
| 168 |
|
|---|
| 169 | Weak symbol support for a.out.
|
|---|
| 170 |
|
|---|
| 171 | A bug in the listing code which could cause an infinite loop has been fixed.
|
|---|
| 172 | Bugs in listings when generating a COFF object file have also been fixed.
|
|---|
| 173 |
|
|---|
| 174 | Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by Paul
|
|---|
| 175 | Kranenburg.
|
|---|
| 176 |
|
|---|
| 177 | Improved Alpha support. Immediate constants can have a much larger range now.
|
|---|
| 178 | Support for the 21164 has been contributed by Digital.
|
|---|
| 179 |
|
|---|
| 180 | Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
|
|---|
| 181 |
|
|---|
| 182 | Changes in 2.3:
|
|---|
| 183 |
|
|---|
| 184 | Mach i386 support, by David Mackenzie and Ken Raeburn.
|
|---|
| 185 |
|
|---|
| 186 | RS/6000 and PowerPC support by Ian Taylor.
|
|---|
| 187 |
|
|---|
| 188 | VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
|
|---|
| 189 | based on mail received from various people. The `-h#' option should work again
|
|---|
| 190 | too.
|
|---|
| 191 |
|
|---|
| 192 | HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work
|
|---|
| 193 | with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special
|
|---|
| 194 | version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve
|
|---|
| 195 | this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
|
|---|
| 196 | in the "dist" directory.
|
|---|
| 197 |
|
|---|
| 198 | Vax support in gas fixed for BSD, so it builds and seems to run a couple simple
|
|---|
| 199 | tests okay. I haven't put it through extensive testing. (GNU make is
|
|---|
| 200 | currently required for BSD 4.3 builds.)
|
|---|
| 201 |
|
|---|
| 202 | Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is
|
|---|
| 203 | based on code donated by CMU, which used an a.out-based format. I'm afraid the
|
|---|
| 204 | alpha-a.out support is pretty badly mangled, and much of it removed; making it
|
|---|
| 205 | work will require rewriting it as BFD support for the format anyways.
|
|---|
| 206 |
|
|---|
| 207 | Irix 5 support.
|
|---|
| 208 |
|
|---|
| 209 | The test suites have been fixed up a bit, so that they should work with a
|
|---|
| 210 | couple different versions of expect and dejagnu.
|
|---|
| 211 |
|
|---|
| 212 | Symbols' values are now handled internally as expressions, permitting more
|
|---|
| 213 | flexibility in evaluating them in some cases. Some details of relocation
|
|---|
| 214 | handling have also changed, and simple constant pool management has been added,
|
|---|
| 215 | to make the Alpha port easier.
|
|---|
| 216 |
|
|---|
| 217 | New option "--statistics" for printing out program run times. This is intended
|
|---|
| 218 | to be used with the gcc "-Q" option, which prints out times spent in various
|
|---|
| 219 | phases of compilation. (You should be able to get all of them printed out with
|
|---|
| 220 | "gcc -Q -Wa,--statistics", I think.)
|
|---|
| 221 |
|
|---|
|
