[Nouveau] [PATCH] libdrm: hide all private symbols
Using -export-symbols-regex all private symbols are hidden, resulting in the following changes: libkms: removes all driver specific exports radeon: removes the bof_* exports nouveau: removes the abi16_* exports freedreno: remove the *kgsl_* and msm_* exports intel: removes the drm_mm* exports omap/exynos: unchanged as far as I can tell Signed-off-by: Maarten Lankhorst <maarten.lankhorst at canonical.com> --- diff --git a/exynos/Makefile.am b/exynos/Makefile.am index 0a2663a..0cd753d 100644 --- a/exynos/Makefile.am +++ b/exynos/Makefile.am @@ -7,7 +7,8 @@ AM_CFLAGS = \ libdrm_exynos_la_LTLIBRARIES = libdrm_exynos.la libdrm_exynos_ladir = $(libdir) -libdrm_exynos_la_LDFLAGS = -version-number 1:0:0 -no-undefined +libdrm_exynos_la_LDFLAGS = -version-number 1:0:0 -no-undefined \ + -export-symbols-regex '^(exynos|g2d)_' libdrm_exynos_la_LIBADD = ../libdrm.la @PTHREADSTUBS_LIBS@ libdrm_exynos_la_SOURCES = \ diff --git a/freedreno/Makefile.am b/freedreno/Makefile.am index 7903e5b..5fdee22 100644 --- a/freedreno/Makefile.am +++ b/freedreno/Makefile.am @@ -9,7 +9,8 @@ AM_CFLAGS = \ libdrm_freedreno_la_LTLIBRARIES = libdrm_freedreno.la libdrm_freedreno_ladir = $(libdir) -libdrm_freedreno_la_LDFLAGS = -version-number 1:0:0 -no-undefined +libdrm_freedreno_la_LDFLAGS = -version-number 1:0:0 -no-undefined \ + -export-symbols-regex '^fd_' libdrm_freedreno_la_LIBADD = ../libdrm.la @PTHREADSTUBS_LIBS@ libdrm_freedreno_la_SOURCES = \ diff --git a/intel/Makefile.am b/intel/Makefile.am index f49b099..2b9ee48 100644 --- a/intel/Makefile.am +++ b/intel/Makefile.am @@ -33,7 +33,8 @@ AM_CFLAGS = \ libdrm_intel_la_LTLIBRARIES = libdrm_intel.la libdrm_intel_ladir = $(libdir) -libdrm_intel_la_LDFLAGS = -version-number 1:0:0 -no-undefined +libdrm_intel_la_LDFLAGS = -version-number 1:0:0 -no-undefined \ + -export-symbols-regex '^drm_intel_' libdrm_intel_la_LIBADD = ../libdrm.la \ @PTHREADSTUBS_LIBS@ \ @PCIACCESS_LIBS@ \ diff --git a/libkms/Makefile.am b/libkms/Makefile.am index 449a73b..e3c727a 100644 --- a/libkms/Makefile.am +++ b/libkms/Makefile.am @@ -5,7 +5,8 @@ AM_CFLAGS = \ libkms_la_LTLIBRARIES = libkms.la libkms_ladir = $(libdir) -libkms_la_LDFLAGS = -version-number 1:0:0 -no-undefined +libkms_la_LDFLAGS = -version-number 1:0:0 -no-undefined \ + -export-symbols-regex '^kms_' libkms_la_LIBADD = ../libdrm.la #if HAVE_LIBUDEV diff --git a/nouveau/Makefile.am b/nouveau/Makefile.am index 206e892..257cab9 100644 --- a/nouveau/Makefile.am +++ b/nouveau/Makefile.am @@ -8,7 +8,8 @@ AM_CFLAGS = \ libdrm_nouveau_la_LTLIBRARIES = libdrm_nouveau.la libdrm_nouveau_ladir = $(libdir) -libdrm_nouveau_la_LDFLAGS = -version-number 2:0:0 -no-undefined +libdrm_nouveau_la_LDFLAGS = -version-number 2:0:0 -no-undefined \ + -export-symbols-regex '^nouveau_' libdrm_nouveau_la_LIBADD = ../libdrm.la @PTHREADSTUBS_LIBS@ libdrm_nouveau_la_SOURCES = nouveau.c \ diff --git a/omap/Makefile.am b/omap/Makefile.am index c77520b..bcbe98e 100644 --- a/omap/Makefile.am +++ b/omap/Makefile.am @@ -7,7 +7,8 @@ AM_CFLAGS = \ libdrm_omap_la_LTLIBRARIES = libdrm_omap.la libdrm_omap_ladir = $(libdir) -libdrm_omap_la_LDFLAGS = -version-number 1:0:0 -no-undefined +libdrm_omap_la_LDFLAGS = -version-number 1:0:0 -no-undefined \ + -export-symbols-regex '^omap_' libdrm_omap_la_LIBADD = ../libdrm.la @PTHREADSTUBS_LIBS@ libdrm_omap_la_SOURCES = omap_drm.c diff --git a/radeon/Makefile.am b/radeon/Makefile.am index a8cd100..9fa19a8 100644 --- a/radeon/Makefile.am +++ b/radeon/Makefile.am @@ -31,7 +31,8 @@ AM_CFLAGS = \ libdrm_radeon_la_LTLIBRARIES = libdrm_radeon.la libdrm_radeon_ladir = $(libdir) -libdrm_radeon_la_LDFLAGS = -version-number 1:0:1 -no-undefined +libdrm_radeon_la_LDFLAGS = -version-number 1:0:1 -no-undefined \ + -export-symbols-regex '^radeon_' libdrm_radeon_la_LIBADD = ../libdrm.la @PTHREADSTUBS_LIBS@ libdrm_radeon_la_SOURCES = \
