* elf16: WIP: support for 16-bit segmented relocations in ELF32elf16H. Peter Anvin2018-12-242-70/+126
| | | | | | | | | | | | | | Add very preliminary support for 16-bit segmented relocations. This does not handle segmented programming in any kind of programmer-friendly way, but it is the beginning to something testable. (Prototype) binutils: URL: https://github.com/hjl-tools/binutils-gdb Branch: users/hjl/16bit Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | AMD documents this instruction with an rax operand. The error behavior implies this is an address-size-sensitive instruction. Add support for specifying the explicit operand, but consistent with normal ndisasm behavior, don't disassemble the implicit operand. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* | With buffered warnings, change the handling of error passesH. Peter Anvin (Intel)2018-12-1815-89/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With buffered warnings, most warnings *must* be issued on every pass, so ERR_PASS1 is simply wrong in most cases. ERR_PASS1 now means "force this warning to be output even in pass_first(). This is to be used for the case where the warning is only executed in pass_first() code; this is highly discouraged as it means the warnings will not appear in the list file and subsequent passes may make the warning suddenly vanish. ERR_PASS2 just as before suppresses an error or warning unless we are in pass_final(). Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | The use of pass0, pass1, pass2, and "pass" passed as an argument is really confusing and already caused a severe bug in the 2.14.01 release cycle. Clean them up and be far more explicit about what various passes mean. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | Try to make nasm_assert() do a static assert if the argument can be evaluated at compile time by any particular compiler. We also provide nasm_try_static_assert() which will assert a compile-time expression if and only if we can determine we have a constant at compile time *and* we know that the compiler has a way to handle it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | ? in identifiers turns out to be used in the field even in non-TASM mode. Resolve this by allowing it in an identifier still, but treat '?' by itself the same as we would a keyword, meaning that it needs to be separated from other identifier characters. In other words: a ? b : c ; conditional expression a?b:c ; seg:off expression seg = a?b, off = c Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>

Buffer warnings on a strlist until we either get an error or we are in pass 2. Hopefully this should let us get rid of a lot of the ERR_PASS* bullshit, which far too often causes messages to get lost. asm/labels.c contains one example of a warning that cannot be made correct with a specific pass number.
