This PR reduces size of linked bitcode, e.g. by removing following symbols: _Z12__clc_sw_fmaDv16_fS_S_ _Z12__clc_sw_fmaDv2_fS_S_ _Z12__clc_sw_fmaDv3_fS_S_ _Z12__clc_sw_fmaDv4_fS_S_ _Z12__clc_sw_fmaDv8_fS_S_ _Z12__clc_sw_fmafff Added: Modified: libclc/cmake/modules/AddLibclc.cmake Removed: ################################################################################ diff --git a/libclc/cmake/modules/AddLibclc.cmake b/libclc/cmake/modules/AddLibclc.cmake index 911559ff4bfa9..2ec6d3256f8a2 100644 --- a/libclc/cmake/modules/AddLibclc.cmake +++ b/libclc/cmake/modules/AddLibclc.cmake @@ -107,9 +107,13 @@ function(link_bc) set( LINK_INPUT_ARG "@${RSP_FILE}" ) endif() + if( ARG_INTERNALIZE ) + set( link_flags --internalize --only-needed ) + endif() + add_custom_command( OUTPUT ${ARG_TARGET}.bc - COMMAND ${llvm-link_exe} $<$<BOOL:${ARG_INTERNALIZE}>:--internalize> -o ${ARG_TARGET}.bc ${LINK_INPUT_ARG} + COMMAND ${llvm-link_exe} ${link_flags} -o ${ARG_TARGET}.bc ${LINK_INPUT_ARG} DEPENDS ${llvm-link_target} ${ARG_DEPENDENCIES} ${ARG_INPUTS} ${RSP_FILE} ) _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
