ZCC 在coremark 有15-20%性能提升（base gcc），但是spec2006上无论怎么配置提升都不大。
hello, sadbread!
可以描述一下你使用 gcc 和 zcc 的配置文件吗？
你好，zcc和gcc用的一样的编译选项
-march=rv64g_zicond_zba_zbb -O3 -falign-functions=32
这是我们调优过的 spec2006 标量/向量的配置文件，你可以尝试一下这些配置。
另外，方便告诉我们，你们在哪个平台上进行测试吗？ 
zcc-linux-rv64imafdc-4.1.1.cfg
# This file comes from https://www.francisz.cn/2021/10/04/spec2006-usage.
# This is a sample config file for CPU2006. It was tested with:
#
# Compiler name/version: [gcc, g++, gfortran 4.3.4]
# [gcc, g++, gfortran 4.4.4]
# [gcc, g++, gfortran 4.6.0]
# Operating system version: [SLES 11 SP1, 64-bit, gcc 4.3.4 and 4.6.0]
# [RHEL 6, 64-bit, gcc 4.4.4]
# Hardware: [Opteron]
#
# If your platform uses different versions, different
# hardware or operates in a different mode (for
# example, 32- vs. 64-bit mode), there is the possibiliy
# that this configuration file may not work as-is.
#
# Note that issues with compilation should be directed
# to the compiler vendor. Information about SPEC techncial
# support can be found in the techsupport document in the
# Docs directory of your benchmark installation.
#
# Also note that this is a sample configuration. It
# is expected to work for the environment in which
# it was tested; it is not guaranteed that this is
# the config file that will provide the best performance.
#
# Note that you might find a more recent config file for
# your platform with the posted results at
# www.spec.org/cpu2006

这些文件配置文件的使用方式如下，
介绍
本目录提供 ZCC 在 SPEC CPU2006 下的配置文件如下：
zcc-linux-rv64imafdc-4.1.1.cfg
zcc-linux-rv64imafdcv-4.1.1.cfg
在 cpu2006 的项目目录下都存在一个 config 目录，将对应 ZCC 的 config 文件拷贝到相应目录，按照 SPEC CPU 官方使用方式指定对应 config 文件。
SPEC CPU2006
SPEC CPU2006 编译使用: Rules SPEC CPU2006
按照网页中的步骤准备好编译环境后，在编译时指定 ZCC 的配置文件即可，比如这里用 zcc-linux-rv64imafdc-4.1.1.cfg 编译 int /fp测试集：
source shrc
runspec --config zcc-linux-rv64imafdc-4.1.1 --action build int
runspec --config zcc-linux-rv64imafdc-4.1.1 --action build fp
NOTE: 对于410.bwaves, 434.zeusmp, 481.wrf 这三个case由于fortran中使用的动态数组分配在栈上导致栈溢出，使用命令ulimit -s unlimited调整操作系统栈大小限制可以解决。
非常感谢。我们测试平台主要包括自研IP核，昆明湖v2以及 Milk-V Jupiter。
我也很关注，是否测试过zcc在xiangshan 昆明湖v3版本中的spec06性能提升吗？
