Tee-Kiah Chia ea8097d866 doc/em/app.codes.nr: fix "139: no real data" error under GNU tbl 
Before the patch, running the GNU tbl(1) preprocessor on the
troff file app.codes.nr would give a warning

	$ tbl app.codes.nr >app.codes.nr.2
	tbl:app.codes.nr:139: no real data
	tbl:app.codes.nr:139: giving up on this table

and the table of suffixes

	.z	no arguments
	.l	16-bit argument
	...	...

would be left out of the tbl output.

Tee-Kiah Chia 64a74b4e09 Add .seek asm pseudo-op, advances location counter to fixed offset 
The new .seek assembler pseudo-op advances the location
counter to a fixed offset within a section --- or to a fixed
address, if the section is a .base'd section.  It works
somewhat like the GNU assembler's .org pseudo-op, though
with a hopefully less confusing name.

This pseudo-op lets us avoid having to manually compute the
needed boot sector padding in the pc86 start-up code
plat/pc86/boot.s .

aslod: fix: use section alignments when computing section sizes
 2021-03-18 19:38:16 +01:00
Tee-Kiah Chia a29507d9e4 aslod: fix: use section alignments when computing section sizes 
The follows( ) function uses pa->os_lign when determining
whether an output section pa immediately follows another
section pb.

However, emits( ) was not using this alignment information
when laying out and padding the output sections.  This seems
to be a bug.

I suspect that mach/arm/cv/cv.c might need a similar fix.

Fix static buffer overflow in genname( ) in LLgen
 2021-03-16 20:37:56 +01:00
Tee-Kiah Chia 9c7ce04cec Fix static buffer overflow in genname( ) in LLgen 
This should fix at least some instances of the "undefined
reference to `LLnc_recover'" error that happens in some
builds (https://github.com/davidgiven/ack/issues/218).

The bug was that genname( ) used a static `namebuf' buffer
and did not properly check for overflow when writing into
it.  The result was that the `non_corr' variable was
sometimes overwritten with a non-zero value when it should
be zero, causing bogus results later.

This proposed patch makes genname( ) dynamically allocate
and resize a buffer for holding a target file name.

I also take this chance to fix a typo in correct_prefix().
