4aa66d9033 * emit a 32-bit offset for DW_FORM_ref_addr on i8086 (Watcom compatibility)

d1cdd8be7c * do not emit padding bytes after the dwarf arange header on i8086 for 
compatibility with Open Watcom (also, the dwarf spec is not very clear about
  the alignment requirements on segmented architectures, so that's why we do
  this by default, instead of putting it behind a -go debug switch)

1a2f364e68 * use 32-bit address_size in the dwarf arange sections on i8086 (for Open Watcom 
compatibility)

fields of the dwarf arange header

a12622e06f * use 1-byte alignment instead of 4-byte alignment for the OMF dwarf sections 
(otherwise the alignment screws up the dwarf debug info)

dcfe1cae13 * fix 4265 cases where the index resolved a lemma that had a link= property. 
Mantis #32325
 * adds a warning for the cases that are fixed. If generation logs are saved, this makes it easy to check if new problems are related to this fix.

1f76f52996 * use hexstr(addr) in the dwarf backtrace function, so it displays always a good 
value, according to the x86 pointer type

git-svn-id: trunk@39057 -
 2018-05-20 14:42:17 +00:00
nickysn

 2018-05-20 13:41:10 +00:00
nickysn
2c000d1e74 * processaddress's type changed to word on i8086 (ptruint changes size between 
memory models and we only need the offset; the segment is tracked separately)
+ introduce texefile.processsegment on i8086
* initialize processaddress and processsegment properly on i8086-msdos (for .exe
  files; .com files are not supported yet)

994783db95 + introduce the TFilePos type for storing file offsets; use longint instead of 
sizeint on i8086, because sizeint is 16-bit and file offsets are 32-bit there

svenbarth
2bf5c28077 + add methods begin_dynarray_const and end_dynarray_const which can be used to emit the data of a dynamic array 
inbetween

nickysn
c8cbb1daea * changed the sechdrofs,secstrofs and ImgOffset types to 32-bit to prevent 
overflow errors on i8086 (ptruint is 16-bit in certain i8086 memory models;
  file offsets, however, still remain 32-bit)

8364b1f4ca * changed the result of function Pos() to SizeInt (same type as the 'index'

537fbefb9e * add texeheader.ImgOffset to all file offsets when reading an ELF file. This 
will be useful for reading i8086-msdos dwarf debug info, because it is
  appended after the regular dos MZ exe in an ELF32 image by the watcom linker.
