From 712060650be4ca4ba6fd84fc4670a12a6cef79b7 Mon Sep 17 00:00:00 2001 From: midipix Date: Tue, 8 Sep 2020 02:29:46 +0000 Subject: driver, link mode: properly implement the -module semantics. Prior to this commit, -module was not respected when the specified output name happened to end with the platform's shared library suffix. In addition, the logic for generating shared libraries with -module in effect has been incomplete and partially also incorrect. --- src/logic/slbt_exec_link.c | 28 +++++++++++++++++++++++++++- 1 file changed, 27 insertions(+), 1 deletion(-) (limited to 'src/logic') diff --git a/src/logic/slbt_exec_link.c b/src/logic/slbt_exec_link.c index 5f94038..88efff2 100644 --- a/src/logic/slbt_exec_link.c +++ b/src/logic/slbt_exec_link.c @@ -1306,6 +1306,15 @@ static int slbt_exec_link_create_library( if ((dctx->cctx->drvflags & SLBT_DRIVER_IMAGE_MACHO)) { (void)0; + } else if (dctx->cctx->drvflags & SLBT_DRIVER_MODULE) { + if ((size_t)snprintf(soname,sizeof(soname),"-Wl,%s", + dctx->cctx->output) + >= sizeof(soname)) + return SLBT_BUFFER_ERROR(dctx); + + *ectx->soname = "-Wl,-soname"; + *ectx->lsoname = soname; + } else if (relfilename && dctx->cctx->verinfo.verinfo) { if ((size_t)snprintf(soname,sizeof(soname),"-Wl,%s%s-%s%s.%d%s", ectx->sonameprefix, @@ -1368,7 +1377,9 @@ static int slbt_exec_link_create_library( } /* output */ - if (relfilename) { + if (dctx->cctx->drvflags & SLBT_DRIVER_MODULE) { + strcpy(output,dctx->cctx->output); + } else if (relfilename) { strcpy(output,relfilename); } else if (dctx->cctx->drvflags & SLBT_DRIVER_AVOID_VERSION) { strcpy(output,dsofilename); @@ -1789,6 +1800,21 @@ int slbt_exec_link( false)) return SLBT_NESTED_ERROR(dctx); + /* dynaic library via -module */ + if (dctx->cctx->drvflags & SLBT_DRIVER_MODULE) { + if (slbt_exec_link_create_library( + dctx,ectx, + ectx->dsobasename, + ectx->dsofilename, + ectx->relfilename)) { + slbt_free_exec_ctx(actx); + return SLBT_NESTED_ERROR(dctx); + } + + slbt_free_exec_ctx(actx); + return 0; + } + /* dynamic library */ if (dot && !strcmp(dot,".la") && dctx->cctx->rpath && !fstaticonly) { /* linking: libfoo.so.x.y.z */ -- cgit v1.2.3
