If you don't know what is AVX, you might want to set "ON". -- `WITH_TEST`: ***Optional, default OFF***. Build unit tests binaries. Once you've built the unit tests, you can run these test manually by the following command: - ```bash - docker run --rm -v $PWD:/paddle -e "WITH_GPU=OFF" -e "WITH_AVX=ON" paddle:dev sh -c "cd /paddle/build; make coverall" - ``` -- `RUN_TEST`: ***Optional, default OFF***.

 and , which are strings
-#        you would put in $PS1 before and after the status string
-#        generated by the git-prompt machinery.  e.g.
-#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
-#          will show username, at-sign, host, colon, cwd, then

-#          your prompt.
-#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
-#          will show username, pipe, then various status string,
-#          followed by colon, cwd, dollar and SP, as your prompt.
-#        Optionally, you can supply a third argument with a printf
-#        format string to finetune the output of the branch status
-#
-# The repository status will be displayed only if you are currently in a
-# git repository. The %s token is the placeholder for the shown status.
-#
-# The prompt status always includes the current branch name.
-#
-# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
-# unstaged (*) and staged (+) changes will be shown next to the branch
-# name.  You can configure this per-repository with the
-# bash.showDirtyState variable, which defaults to true once
-# GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-# You can also see if currently something is stashed, by setting
-# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-# then a '$' will be shown next to the branch name.
-#
-# If you would like to see if there're untracked files, then you can set
-# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
-# files, then a '%' will be shown next to the branch name.  You can
-# configure this per-repository with the bash.showUntrackedFiles
-# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
-# enabled.
-#
-# If you would like to see the difference between HEAD and its upstream,
-# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
-# indicates you are ahead, "<>" indicates you have diverged and "="
-# indicates that there is no difference. You can further control
-# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
-# of values:
-#
-#     verbose       show number of commits ahead/behind (+/-) upstream
-#     legacy        don't use the '--count' option available in recent
-#                   versions of git-rev-list
-#     git           always compare HEAD to @{upstream}
-#     svn           always compare HEAD to your SVN upstream
-#
-# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
-# find one, or @{upstream} otherwise.  Once you have set
-# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
-# setting the bash.showUpstream config variable.
-#
-# If you would like to see more information about the identity of
-# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
-# to one of these values:
-#
-#     contains      relative to newer annotated tag (v1.6.3.2~35)
-#     branch        relative to newer tag or branch (master~4)
-#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
-#     default       exactly matching tag
-#
-# If you would like a colored hint about the current dirty state, set
-# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
-# the colored output of "git status -sb" and are available only when
-# using __git_ps1 for PROMPT_COMMAND or precmd.

+#        the optional argument will be used as format string.
+#    3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+#        be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
+#        with two parameters, 
 and , which are strings
+#        you would put in $PS1 before and after the status string
+#        generated by the git-prompt machinery.  e.g.
+#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+#          will show username, at-sign, host, colon, cwd, then
+#          various status string, followed by dollar and SP, as
+#          your prompt.
+#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
+#          will show username, pipe, then various status string,
+#          followed by colon, cwd, dollar and SP, as your prompt.
+#        Optionally, you can supply a third argument with a printf
+#        format string to finetune the output of the branch status
+#
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
+#
+# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
+# unstaged (*) and staged (+) changes will be shown next to the branch
+# name.  You can configure this per-repository with the
+# bash.showDirtyState variable, which defaults to true once
+# GIT_PS1_SHOWDIRTYSTATE is enabled.
+#
+# You can also see if currently something is stashed, by setting
+# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
+# then a '$' will be shown next to the branch name.
+#
+# If you would like to see if there're untracked files, then you can set
+# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
+# files, then a '%' will be shown next to the branch name.  You can
+# configure this per-repository with the bash.showUntrackedFiles
+# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
+# enabled.
+#
+# If you would like to see the difference between HEAD and its upstream,
+# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
+# indicates you are ahead, "<>" indicates you have diverged and "="
+# indicates that there is no difference. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
+# of values:
+#
+#     verbose       show number of commits ahead/behind (+/-) upstream
+#     legacy        don't use the '--count' option available in recent
+#                   versions of git-rev-list
+#     git           always compare HEAD to @{upstream}
+#     svn           always compare HEAD to your SVN upstream
+#
+# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
+# find one, or @{upstream} otherwise.  Once you have set
+# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
+# setting the bash.showUpstream config variable.
+#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+#     contains      relative to newer annotated tag (v1.6.3.2~35)
+#     branch        relative to newer tag or branch (master~4)
+#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+#     default       exactly matching tag
+#
+# If you would like a colored hint about the current dirty state, set
+# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd.

Subject: [PATCH 31/40] Simpily demo, add paddle.default_main_program() and
 paddle.default_startup_program

- Removed all main_program and startup_program in the demo.
- Using paddle.default_main_program() hides the implementation detail (e.g., using g_main_program) from the user, we can change the implementation in the future much easier.
