Hi, in order to fix PR64331 I tried to implement new target-specific passes
whose sole purpose is to recompute REG_DEAD notes.
The avr BE relies on correct dead notes which are used in
avr.c:reg_unused_after which uses dead_or_set_p. avr BE needs correct dead
notes in ADJUST_INSN_LENGTH, get_attr_length, get_attr_min_length, etc.
After trying for more than one day I am really frustrated; each approach
ended up in seg_faults somewhere in df.
Following the source comments in df-core.c, recomputing dead notes should be
as easy as
df_note_add_problem ();
df_analyze ();
in the execute() method of the new pass.
As this (and many many other tries using df_scan_alloc, df_scan_blocks
df_finish_pass, df_insn_rescan_all, etc.) always crashes the compiler, I must
do something completely wrong...
Could you give me some advice on correct usage of df or even more preferred
point me to a comprehensible documentation of df which is more complete than
in df-core.c?
Hi, thanks for answering.
It is generally as easy as just adding the problem and calling df_analyze.
You tend to get into trouble if the rtl is not good, i.e. there is improper
sharing or other violations of the canonical rtl rules. DF does not like
improperly shared rtl and it has not been uncommon for port specific passes to
play loose with these rules.
Currently there are no port-specific passes. The only port-specific passes are
the new passes which I am trying to add in order to keep REG_DEAD notes up to date.
I would suggest that first you try a build where you turn on all of the rtl
checking and see if that comes out clean.

Okay, here we go. I configured avr-gcc from recent 4.9-branch with
--enable-checking=all on x86-linux-gnu:
$ ../../gcc.gnu.org/gcc-4_9-branch/configure --target=avr
--prefix=/local/gnu/install/gcc-4.9 --disable-nls --with-dwarf2
--enable-target-optspace=yes --with-gnu-ld --with-gnu-as
--enable-languages=c,c++ --enable-checking=all
The passes are added by means of the attached patch and installed right before
passes which might use avr.c:reg_unused_after, i.e. passes that query for
(minimum) insn lengths: .bbro, .compgotos, .shorten and .final.
The compiler crashes when it builds libgcc. The test case is attached as
libgcc2-addvsi3.c and compiled as
$ path-to-xgcc/xgcc -B path-to-xgcc -S libgcc2-addvsi3.c
The crash message (same with optimization) is for the pass which has been added
just before .shorten:
libgcc2-addvsi3.c: In function '__addvhi3':
libgcc2-addvsi3.c:1514:1: internal compiler error: in df_refs_verify, at
