I re-configured with exactly the same command line options, except I removed
ada from "--enable-languages=", and re-started make.


On this second attempt the file building timing was similar to what was
previously reported. It appears the link time was 20 minutes here:

# ls -lrtA gcc-4_3-build-profile-1/prev-gcc/
...
-rw-r--r--  1 root root     2108 Jul  2 06:32 crtbeginS.o
-rw-r--r--  1 root root     1672 Jul  2 06:32 crtbegin.o
-rw-r--r--  2 root root     3904 Jul  2 06:53 tlink.gcda
-rw-r--r--  2 root root     5968 Jul  2 06:53 collect2.gcda
-rw-r--r--  2 root root     1360 Jul  2 07:13 web.gcda
-rw-r--r--  2 root root      688 Jul  2 07:13 vec.gcda
all the remaining 'data files' had the same time - at leasr that was fast as
was the last successful pass in gcc-4_3-build-profile-1/gcc .


Here is where it broke:

On my first attempt I typed this, and I got this:

# grep Configuring\ stage gcc-4_3-build-profile-1/make_29a_log.txt
Configuring stage 1 in ./intl
Configuring stage 1 in ./gcc
Configuring stage 1 in ./libiberty
Configuring stage 1 in ./zlib
Configuring stage 1 in ./libcpp
Configuring stage 1 in ./libdecnumber
Configuring stage 1 in i686-pc-linux-gnu/libgcc
Configuring stage profile in ./intl
Configuring stage profile in ./gcc
Configuring stage profile in ./libiberty
Configuring stage profile in ./zlib
Configuring stage profile in ./libcpp
Configuring stage profile in ./libdecnumber


On my second attempt I typed this, and I got this:

# grep Configuring\ stage opt/gcc-4_3-build-profile-1/make_29b_log.txt 
Configuring stage 1 in ./libiberty
Configuring stage 1 in ./zlib
Configuring stage 1 in ./libcpp
Configuring stage 1 in ./libdecnumber
Configuring stage profile in ./intl
Configuring stage profile in ./gcc
Configuring stage profile in ./libiberty
Configuring stage profile in ./zlib
Configuring stage profile in ./libcpp
Configuring stage profile in ./libdecnumber
Configuring stage profile in i686-pc-linux-gnu/libgcc
Configuring stage feedback in ./intl
Configuring stage feedback in ./gcc
Configuring stage feedback in ./libiberty
Configuring stage feedback in ./zlib
Configuring stage feedback in ./libcpp
Configuring stage feedback in ./libdecnumber


On my first attempt I typed this, and I got this:

# grep execution\ counts\ estimated
/opt/gcc-4_3-build-profile-1/make_29a_log.txt
(prints nothing)

On my second attempt I typed that, and I got a huge list which is attached.


The build ultimatly breaks here:

echo timestamp > s-genrtl
