From fb429ec409348501f6ab1932b39ee2d612723198 Mon Sep 17 00:00:00 2001 From: Oran Agra Date: Sun, 5 Apr 2009 18:08:32 +0300 Subject: [PATCH] Position Independent Code (PIC) support in sfnt driver. * include/freetype/internal/services/svbdf.h add macros to init instances of FT_Service_BDFRec. * include/freetype/internal/services/svgldict.h add macros to init instances of FT_Service_GlyphDictRec. * include/freetype/internal/services/svpostnm.h add macros to init instances of FT_Service_PsFontNameRec. * include/freetype/internal/services/svsfnt.h add macros to init instances of FT_Service_SFNT_TableRec. * include/freetype/internal/services/svttcmap.h add macros to init instances of FT_Service_TTCMapsRec. * include/freetype/internal/sfnt.h add macros to init instances of SFNT_Interface. * src/sfnt/sfdriver.h declare sfnt_module_class using macros from ftmodapi.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/sfnt/sfdriver.c when FT_CONFIG_OPTION_PIC is defined the following structs: sfnt_service_sfnt_table, sfnt_service_glyph_dict, sfnt_service_ps_name tt_service_get_cmap_info, sfnt_service_bdf, sfnt_interface, sfnt_module_class, and sfnt_services array will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from sfntpic.h in order to access them from the pic_container. * src/sfnt/ttcmap.h add macros to init instances of TT_CMap_ClassRec. * src/sfnt/ttcmap.c when FT_CONFIG_OPTION_PIC is defined the following structs: tt_cmap0_class_rec, tt_cmap2_class_rec, tt_cmap4_class_rec tt_cmap6_class_rec, tt_cmap8_class_rec, tt_cmap10_class_rec, tt_cmap12_class_rec, tt_cmap14_class_rec and tt_cmap_classes array will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from sfntpic.h in order to access them from the pic_container. The content of tt_cmap_classes is now described in the new file 'ttcmapc.h'. New Files: * src/sfnt/sfntpic.h declare struct to hold PIC globals for sfnt driver and macros to access them. * src/sfnt/sfntpic.c implement functions to allocate, destroy and initialize PIC globals for sfnt driver. * src/sfnt/ttcmapc.h describing the content of tt_cmap_classes allocated in ttcmap.c * src/sfnt/sfnt.c add new file to build: sfntpic.c. * src/sfnt/jamfile add new files to FT2_MULTI build: sfntpic.c. --- ChangeLog | 55 ++++++ include/freetype/internal/services/svbdf.h | 20 +++ include/freetype/internal/services/svgldict.h | 22 +++ include/freetype/internal/services/svpostnm.h | 21 +++ include/freetype/internal/services/svsfnt.h | 21 +++ include/freetype/internal/services/svttcmap.h | 21 +++ include/freetype/internal/sfnt.h | 135 ++++++++++++++ src/sfnt/Jamfile | 2 +- src/sfnt/sfdriver.c | 166 ++++++++---------- src/sfnt/sfdriver.h | 2 +- src/sfnt/sfnt.c | 1 + src/sfnt/sfntpic.c | 101 +++++++++++ src/sfnt/sfntpic.h | 88 ++++++++++ src/sfnt/ttcmap.c | 160 ++++++++--------- src/sfnt/ttcmap.h | 40 +++++ src/sfnt/ttcmapc.h | 55 ++++++ 16 files changed, 735 insertions(+), 175 deletions(-) create mode 100644 src/sfnt/sfntpic.c create mode 100644 src/sfnt/sfntpic.h create mode 100644 src/sfnt/ttcmapc.h diff --git a/ChangeLog b/ChangeLog index 1895ee93..a46eaafb 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,58 @@ +2009-04-05 Oran Agra + + Position Independent Code (PIC) support in sfnt driver. + + * include/freetype/internal/services/svbdf.h add macros to init + instances of FT_Service_BDFRec. + * include/freetype/internal/services/svgldict.h add macros to init + instances of FT_Service_GlyphDictRec. + * include/freetype/internal/services/svpostnm.h add macros to init + instances of FT_Service_PsFontNameRec. + * include/freetype/internal/services/svsfnt.h add macros to init + instances of FT_Service_SFNT_TableRec. + * include/freetype/internal/services/svttcmap.h add macros to init + instances of FT_Service_TTCMapsRec. + * include/freetype/internal/sfnt.h add macros to init + instances of SFNT_Interface. + + * src/sfnt/sfdriver.h declare sfnt_module_class using macros from + ftmodapi.h, when FT_CONFIG_OPTION_PIC is defined create and destroy + functions will be declared. + * src/sfnt/sfdriver.c when FT_CONFIG_OPTION_PIC is defined + the following structs: + sfnt_service_sfnt_table, sfnt_service_glyph_dict, sfnt_service_ps_name + tt_service_get_cmap_info, sfnt_service_bdf, sfnt_interface, + sfnt_module_class, and sfnt_services array + will have functions to init or create and destroy them + instead of being allocated in the global scope. + And macros will be used from sfntpic.h in order to access them + from the pic_container. + + * src/sfnt/ttcmap.h add macros to init + instances of TT_CMap_ClassRec. + * src/sfnt/ttcmap.c when FT_CONFIG_OPTION_PIC is defined + the following structs: + tt_cmap0_class_rec, tt_cmap2_class_rec, tt_cmap4_class_rec + tt_cmap6_class_rec, tt_cmap8_class_rec, tt_cmap10_class_rec, + tt_cmap12_class_rec, tt_cmap14_class_rec and tt_cmap_classes array + will have functions to init or create and destroy them + instead of being allocated in the global scope. + And macros will be used from sfntpic.h in order to access them + from the pic_container. + The content of tt_cmap_classes is now described in the + new file 'ttcmapc.h'. + + New Files: + * src/sfnt/sfntpic.h declare struct to hold PIC globals for sfnt + driver and macros to access them. + * src/sfnt/sfntpic.c implement functions to allocate, destroy and + initialize PIC globals for sfnt driver. + * src/sfnt/ttcmapc.h describing the content of + tt_cmap_classes allocated in ttcmap.c + + * src/sfnt/sfnt.c add new file to build: sfntpic.c. + * src/sfnt/jamfile add new files to FT2_MULTI build: sfntpic.c. + 2009-04-05 Oran Agra Position Independent Code (PIC) support in truetype driver. diff --git a/include/freetype/internal/services/svbdf.h b/include/freetype/internal/services/svbdf.h index 0f7fc611..92642391 100644 --- a/include/freetype/internal/services/svbdf.h +++ b/include/freetype/internal/services/svbdf.h @@ -45,6 +45,26 @@ FT_BEGIN_HEADER FT_BDF_GetPropertyFunc get_property;
