toy frontend

toy frontend

[Oskar Liljeblad]

I am trying out Michael Meeks' modified toy frontend with
GCC 3.0.1 ( http://primates.ximian.com/~michael/toy-3.1.1.tar.gz ),
but I'm getting some errors:

  test.toy: In function `a':
  test.toy:0: Internal compiler error in identify_blocks_1, at function.c:5777
  Please submit a full bug report,
  with preprocessed source if appropriate.
  See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

The stack trace is this:

#1  0x0806e233 in identify_blocks_1 (insns=0x401a2d00, block_vector=0x82a9eec, 
    end_block_vector=0x82a9eec, orig_block_stack=0x82a9f28)

    at ../../gcc-3.0.1/gcc/toplev.c:4990
#8  0x4004064f in __libc_start_main () from /lib/libc.so.6

Also, what is more strange, is that when I run cc1toy without arguments,
I get a segmentation fault. This time the stack trace is:

#0  0x4009a31f in strlen () from /lib/libc.so.6
#1  0x0804b915 in output_file_directive (asm_file=0x4013b4c0, input_name=0x0)

#3  0x0804fde6 in main (argc=1, argv=0xbffff9e4)
    at ../../gcc-3.0.1/gcc/toplev.c:4992
#4  0x4004064f in __libc_start_main () from /lib/libc.so.6

Could this be due to a malformed lang-specs.h?

Ah, this :) I got this when toplevel expressions wasn't BIND_EXPR.
So simply wrapping function body in it should work.

init_parse() doesn't check if it gets a name, or NULL (for stdin).
This can be easly fixed.

I guess not.

Toy FrontEnd

[khalid aggag]

Hello,

I am interested in building a new frontend for gcc. To start out I am trying 
to compile Michael Meeks' modified toy frontend with
GCC 3.1.1 (http://primates.ximian.com/~michael/toy-3.1.1.tar.gz), I get some 
strange
errors:-

gcc -c -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes 
-Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H 
-DGENERATOR_FILE    -I. -I. -I.././../GCCSRC/gcc -I.././../GCCSRC/gcc/. 
-I.././../GCCSRC/gcc/config -I.././../GCCSRC/gcc/../include 
.././../GCCSRC/gcc/print-rtl.c -o print-rtl.o
In file included from .././../GCCSRC/gcc/print-rtl.c:30:
../../GCCSRC/gcc/tree.h:332:24: tree-check.h: No such file or directory
make[1]: *** [print-rtl.o] Error 1
make[1]: Leaving directory `/home/khalid/Compiler/GCC/GCCOBJ/gcc'
make: *** [all-gcc] Error 2

I checked to see if this "tree-check.h" file exists and i didnt find it. I 
cant understand how
the "tree.h" file includes a file that doesnt actually exits. Can anyone 
help
me please, thanx alot.

Khalid Aggag
