Unfortunately, bisecting did not find anything. Even rebuilding 4.2-53-
gf6dc544 with the same config does not produce an image without the
longer time.
I build 4.2-775-gd91b1df on Debian 8.2 (Jessie/stable) with GCC 4.9.2
and that gave an image with the smaller boot time.
```
asrock/e350m1/4.2-775-gd91b1df/2016-01-16T22:33:45Z/coreboot_timestamps.txt: 0:1st timestamp 657,822
```
I even built an image with the coreboot toolchain, which currently has
GCC 5.2.0, which gave an incorrect image.
```
asrock/e350m1/4.2-840-g967881d/2016-01-19T20:42:27Z/coreboot_timestamps.txt: 0:1st timestamp 1,238,918
```
So my current theory is, that there was a change/regression in GCC
causing the longer boottime.
So I thought to force using GCC 4.9 on my Debian Sid system with the
package gcc-4.9 installed.
I ran `make CC=gcc-4.9` but this resulted again in an image with the
longer boot time.
Could you please help me?
1. How do I make sure that GCC 4.9 is used in `make CC=gcc-4.9`?
I have the x64 toolchain installed.
```
$ ls util/crossgcc/xgcc/bin/
x86_64-elf-addr2line x86_64-elf-dwp x86_64-elf-gcc-nm x86_64-elf-ld.bfd x86_64-elf-ranlib
x86_64-elf-ar x86_64-elf-elfedit x86_64-elf-gcc-ranlib x86_64-elf-ld.gold x86_64-elf-readelf
x86_64-elf-as x86_64-elf-gcc x86_64-elf-gcov x86_64-elf-nm x86_64-elf-size
x86_64-elf-c++filt x86_64-elf-gcc-4.9.2 x86_64-elf-gprof x86_64-elf-objcopy x86_64-elf-strings
x86_64-elf-cpp x86_64-elf-gcc-ar x86_64-elf-ld x86_64-elf-objdump x86_64-elf-strip
```
I attached `.xcompile`.
Randomly, I grepped through some files under `build/` and found the
following.
```
$ strings build/cbfs/fallback/romstage.debug | grep -i gcc
gcc.c
gcc-intrin.h
gcc-intrin.h
gcc-intrin.h
gcc-intrin.h
gcc-intrin.h
../../../../gcc-4.9.2/libgcc
libgcc2.c
libgcc2.h
../../../../gcc-4.9.2/libgcc
libgcc2.c
libgcc2.h
src/lib/gcc.c
/mnt/coreboot/util/crossgcc/build-x86_64-elf-GCC/x86_64-elf/32/libgcc
GNU C 4.9.2 -m32 -mtune=generic -march=x86-64 -g -O2 -O2 -O2 -fbuilding-libgcc -fno-stack-protector -fpic -fexceptions -fnon-call-exceptions -fvisibility=hidden
../../../../gcc-4.9.2/libgcc/libgcc2.c
libgcc2.c
gcc.c
```
So what compiler is used? I’d like to use the distribution toolchain.
2. Is it easy to add the coreboot toolchain information to the log like
SeaBIOS does?
```
asrock/e350m1/4.2-566-g929b602/2015-12-10T23:20:08Z/coreboot_console.txt:BUILD: gcc: (Debian 5.2.1-26) 5.2.1 20151125 binutils: (GNU Binutils for Debian) 2.25.90.20151125
```
3. If it is indeed a compiler issue, how would the debugging go?
Thanks,
Paul
