2014-05-09options: Add --v optionCyrill Gorcunov1-4/+13
It's been requested a long ago to handle '--v' option same was as a regualar '-v'. From initial report | NASM and yasm are in many respects compatible but yasm uses --v | instead of -v for version. As often --v is used for version I | end up using --v initially in NASM. This patch allows me to compile | Mozilla apps which use yasm with NASM by merely renaming NASM to yasm | so that the build environment does not have to be updated (Mozilla | would not accept changes to allow use of NASM).

2013-12-04bnd: Add a new nobnd prefixJin Kyu Song1-1/+8
bnd and nobnd prifixes can be used for each instruction line to direct whether bnd registers should be preserved or not. And those are also added as options for DEFAULT directive. Once bnd is set with default, DEFAULT BND, all bnd-prefix available instructions are prefixed with bnd. To override it, nobnd prefix can be used. In the other way, DEFAULT NOBND can disable DEFAULT BND and have nasm encode in the normal way. Signed-off-by: Jin Kyu Song <jin.kyu.song@intel.com>
2013-12-04bnd: Show warning when bnd prefix is droppedJin Kyu Song1-0/+1
When bnd prefix is dropped as jmp is encoded as jmp short, nasm shows a warning message, which can be suppressed with a new command line option, -w-bnd. Signed-off-by: Jin Kyu Song <jin.kyu.song@intel.com>

2013-08-28AVX-512: Change the data type for instruction flagsJin Kyu Song1-4/+4
Increased the size of data type for instruction flags from 32bits to 64bits. And a new type (iflags_t) is defined for better maintainability. Bigger data type is needed because more instruction set types are coming but there were not enough space for them. Since they are not bit masks, only one instruction set is allowed for each instruction. Signed-off-by: Jin Kyu Song <jin.kyu.song@intel.com> Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>

2012-02-24nasm.c: Fix is_suppressed_warning()H. Peter Anvin1-8/+5
The logic in is_suppressed_warning() was severely wrong, which would cause a lot of legitimate warnings to be suppressed while some warnings would be duplicated. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

2011-04-06ofmt: Alias shortname must be used for __OUTPUT_FORMAT__ macroCyrill Gorcunov1-3/+9
__OUTPUT_FORMAT__ must consist of shortname of output format or its alias, otherwise userspace ABI gets broken. For example source code still can refer to __OUTPUT_FORMAT__=elf, instead of __OUTPUT_FORMAT__=elf32. BR3246990 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>

2010-07-25Revert "Improve process_ea and introduce -OL"H. Peter Anvin1-16/+7
This reverts commit ac732cb6a599836bf4c988e59ac6de4498758c72. Resolved Conflicts: doc/nasmdoc.src Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2010-07-24Improve process_ea and introduce -OLVictor van den Elzen1-7/+16
Two fixes: 1. Optimization of [bx+0xFFFF] etc 0xFFFF is an sbyte under 16-bit semantics, so make sure to check it right. 2. Don't optimize displacements in -O0 Displacements that fit into an sbyte or can be removed should *not* be optimized in -O0. Implicit zero displacements are still optimized, e.g.: [eax] -> 0 bit displacement, [ebp] -> 8 bit displacement. However explicit displacements are not optimized: [eax+0] -> 32 bit displacement, [ebp+0] -> 32 bit displacement. Because #2 breaks compatibility with 0.98, I introduced a new optimization level: -OL, legacy.
2010-07-15Make -Ox the defaultH. Peter Anvin1-5/+14
Make -Ox the default; it's the optimization level expected by most users, and it is clearly still causing confusion that it has to be specified manually. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

2010-04-06Distinguish no directive present from unknown directiveH. Peter Anvin1-4/+4
Distinguish the case of no directive present (D_none) from the case of an unknown specified directive (D_unknown). This is reflected in different error messages. Furthermore, change the special case symbols to lower case in case we ever have a directive called [none] or [unknown]. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2010-01-09nasm.c: Restore strings broken by `indent`Cyrill Gorcunov1-30/+14
A number of strings are broken by nindent passed over the nasm.c. Though the compiler doesn't care about this fact it's really unpleasant to have a string split at "dot" symbol. Lets restore it in a sake of readability. (No change on binary level) Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>
2009-12-04nasm.c: Use copy_filename to set error message fileCyrill Gorcunov1-1/+1

2009-10-31stdscan: switch to stdscan_get/set routinesCyrill Gorcunov1-2/+2
Instead of manipulating stdscan buffer pointer directly we switch to a routine interface. This allow us to unify stdscan access: ie caller should "talk" to stdscan via stdscan_get/set routines. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>

By analogy with nasm_zap_spaces_rev() have nasm_zap_spaces_fwd(). The forward version isn't a super-common operation, and it might be possible to think the reverse one is the "normal" version... therefore we might as well be explicit. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
